Onefinity Conversion.

cncnutz · Nov 27, 2022

With the release of the Onefinity machines using the MASSO Touch controller we have received a lot of questions from existing Onefinity machine users wanting to know if they can upgrade their machines to use MASSO as well.

The answer is yes and several members of this Forum have already done so.
Please use this topic to discuss upgrade requirements and if you do an upgrade why not start a new topic showing your machine conversion process.
That way everyone can learn from each other.

It is important to understand that MASSO does not supply an upgrade kit for the OneFinity machine so it is not a plug and play process.
It is a machine conversion like any other where the installer needs to assess the current hardware and work out what they want to reuse and what to upgrade.

You will need to have and complete correct wiring for the following components

Masso controller
Power supply for the MASSO Controller
Masso closed loop stepper motors, or your own separate stepper motors and drivers
Power supply for motors/drivers
Masso homing sensors, or those of your own choosing
Custom mounts to attach your chosen homing sensors
*Masso relay module for Estop and other functions is highly recommended
*Masso pendant, to replace the joypad functionality if a pendant is wanted

To help with this we created a FAQ section that deals with the common questions related to upgrading a machine and it is a good starting point.

Machine conversion and Builds

docs.masso.com.au

Below I have listed a selection of parts that we can supply that you may wish to consider for your conversion. You may not want or need them all as you may wish to reuse existing hardware or use alternative components.

MASSO Touch, 3 or 5 axis depending on if you want auto squaring
Please see the link below in Axis slaving to better understand why you might want 3 or 5 axis.

Slave Axis

docs.masso.com.au

MASSO closed loop stepper motors
MASSO can provide closed loop stepper motors in 2Nm and 3Nm versions.

MASSO Closed Loop Stepper Motors

docs.masso.com.au

MASSO Relay module
The MASSO relay module will provide 6 relays which can be used to disable motor drives in and emergency and can be used for other functions.

MASSO Relay Module

docs.masso.com.au

MASSO Homing sensor
1 homing sensor is required per axis
If using the 3 axis MASSO version only 3 sensors are required as a single sensor will do the Y axis however if using the 5 Axis MASSO then 4 sensors will be required as both sides of the Y axis will require a sensor for auto squaring.

MASSO Homing Sensor

docs.masso.com.au

24 volt power supply
This is use to power the MASSO controller

Powering MASSO-G3

docs.masso.com.au

36 volt power supply for the MASSO closed loop stepper motors
A 36 volt power supply will be requited to power the MASSO closed loop stepper motors if you are using them.

MASSO Pendant
If you want a pendant MASSO can provide one.
Please note that while many pendants can look the same on the outside, internally they can be very different

MPG Pendant

Questions

1) I see the G3 only has one USB port for a flash drive with the program files on it. Is there any way to use a USB hub to turn that one USB port into 2 or more? If so im curious to know if there is support for something like a webcam or a wireless controller for jogging the machine.
MASSO Touch has 4 USB ports in total and there are 2 spare inside the case.
MASSO does not support Webcam or a Wireless USB pendent of any type.
The USB ports support Flashdrive, Keyboard, mouse, USB Hub and barcode scanner for reading QR codes.

2) If there is no support for the above question i see you sell a wired MPG pendant and see it hooks up to the controller that is inside the HMI housing. Wondering how that works. Is there a hole in the side of the housing for the wire to pass through? I cant tell in the pictures.
There is a large slot in the rear of MASSO Touch to bring the cables through and an insert to seal the hole once you have completed your conversion.
https://docs.masso.com.au/wiring-and-setup/setup-and-calibration/mounting-and-mechanical-data

3) Lastly do you have any tool setters you recommend that will work without issue?
We have no specific recommendations for a tool setter. The key thing with a tool setter is to choose something that has high repeatability.

Okay- I am new to Onefinity - ordered pre Massos Upgrade I just received my machine two weeks ago and then they come out with the new announcement that they now have a MASSO controller version as of two days ago… You folks say that many 1F folks have already made the conversion. I have to assume that was before the OneFinity announcement. Would those who have made the conversion say that it would be best to get OneFinity to honor their infinite possibilities claim and help me do the conversion or do as you folks have done and attempt the conversion on my own?

I built a custom ATC CNC off the Onefinity Woodworker using Masso as my controller. If you are new to Onefinity, and do not want to spend time sourcing, installing, and correctly wiring components I would go through Onefinity. Masso's documentation is excellent, but Onefinity will do all the work and at an exceptional price point for what you are getting. It will also give you time to better understand and use the CNC/CAD/CAM etc..., which will help once you make the switch to Masso.

Question

What spindle should I use with my machine or can I use my existing Laminate trimmer.

MASSO can be used with a range of spindles ranging from laminate trimers to full VFD controlled spindles.
The choice of spindle will depend on your spindle power requirements and the physical limitations of that can fit in the spindle mount on the Z axis, assuming that you do not want to change or modify it.

Laminate trimmer connection.
A solid state relay is a good option to turning an AC Laminate trimmer which simply needs to be turned on and off.
It is optically isolated and can be moved away from other circuits and protected from accidental contact by the user by shielding it within the enclosure. An example of how a Solid state relay can be connected to MASSO is shown below

Solid State drive for Spindle control - This example circuit is intended for an AC Router, laminate trimmer or single phase AC motor used as spindle.

Spindle

MASSO can control a range of spindles using 0-10 volt, PWM or Step and direction signaling.
You can used Water or air cooled either manual or auto tool change spindles.
VFD's use 0-10 volt for speed control with separate FWD & REV inputs if 2 directions of rotation is needed.

The page below show various spindle control options that can be configured.

Question

Can I connect an LED Laser to MASSO to use with a Onefinity machine.
The laser you choose for your install must support PWM.
This is the most common connection method for LED lasers.
Connecting a laser can be done only 2 wires.

Please have a look at our quick start install guides for laser install.
https://docs.masso.com.au/quick-start-guides/laser-engraving-cutting

If you have laser from OptLasers this page shows the connection method.

Installing an Opt Laser

docs.masso.com.au

One of the more popular laser software packages is Lightburn.
This page shows how wo set up lightburn to work with MASSO
https://docs.masso.com.au/quick-start-guides/laser-engraving-cutting/setting-up-lightburn

How to connect an laser to MASSO and configuring.
The configuration and setup information is relevant to all laser installs.

For those using a Onefinity JTech laser module here is a wiring diagram of how it would connect to MASSO.
The Laser Up/Down and Air assist are optional.

We are working closely with Onefinity to provide a completely "plug and play" VFD-Enclosure/Spindle Kit. We will of course be supporting it 100% so you will be able to spend your time into learning and using your Onefinity Elite. PwnCNC is very excited to be a part of this project. Bringing the Masso controller to the bench top cnc community is one of biggest advancements EVER. It opens up opportunities for a whole range of things. Doing away with those silly wrenches

are one thing that comes to mind.

Question: Could I use my Onefinity monitor since it has an HDMI interface?

The MASSO touch used by Onefinity has an integrated touch screen and no HDMI output to connect a monitor.

The MASSO G3 has VGA output only so if your monitor does not include VGA input you will need a VGA to HDMI adapter to use it.
I do not know if the Onefinity monitor is touch screen but please be aware that MASSO G3 supports a very limited range of touch screens.

My recommendation is that if you want a touch screen then get MASSO Touch.
If you want to use a normal monitor with Keyboard and mouse then MASSO G3 may be worth considering.
Note: MASSO Touch can be used with keyboard and mouse as well if you want.

Question: The Onefinity uses stall homing. Does your system have this option?

While not ideal you can use this method with MASSO to home your machine.
By simply leaving the sequence table blank in the Homing screen, MASSO will call whatever location you are at when you home your machine your home position.
To use stall homing simply jog to your defined home position and double click the home button.

Question: Can I use my existing Onefinity stepper motors?

So long as your stepper motor drives support Step and direction your existing motors will work with MASSO.

FAQ

Wiring Examples

Axis Servo/Stepper examples

docs.masso.com.au

Question: Can I upgrade to the closed loop stepper motors you offer? What is the advantage?

Yes, you can use MASSO closed loop stepper motor.
The MASSO Closed loop stepper motors use differential signaling which has high noise immunity. Being closed loop they will not loose steps under normal machining conditions and halt MASSO should an incident such as a crash occurs that does cause positional loss.

Question: Can I Slave the Y axis on my machine
There are 2 options available for slaving. Hardware and Software slaving.
If you choose Software slaving the 5 axis version MASSO is required and both the Y & B axis will require homing sensors to be fitted as this is used for the Auto squaring function.

Here is a video of a machine build and a review of the finished machine.
It may give some ideas to those wanting to build their own.

How do I change tool on a OneFinity Machine?

The Tool setter is used for all tool changers.
Even when you manually do the tool change, you become the tool changer, after all a tool changer just removes the old tool and puts the new tool in the collet.

When you start MASSO it homes and measures the tool on the tool setter.
You Zero your tool on the surface of the material and zero the DRO using any method you like. Eye, Paper,Probe.
Start machining.
Everything is automatic from then on.
When a tool change is called it will move to the dedicated tool change position and request the new tool.

You install the new tool and press cycle start.

The spindle will move to the tool setter, measure the tool length and resume cutting.

It will automatically calculate the difference between the tool lengths and set the Z zero for you.

If your spindle had fixed collets so that each tool length is fixed then you can pre-measure each one and store it in the F4 tool table.

This way you can avoid using the tool setter during tool changes as each tool length is known.

This is an old video of the G2 showing the tool change process but the principle is the same for the G3.

THANK YOU SOOOO MUCH.
I hate to be so inexperienced with the Masso. Trying to support our spindles and answer these questions is really tough. I can't wait to get my hands on the Masso. It has been my dream controller for years. I have your series basically memorized.

Hello,

I see Onefinity is going to offer a stepper motor with brake on it to stop the spindle drop problem many of us are having with the Z-20 Z axis. Is that something you will be offering also? I have the 3Nm steppers.

Second this, even the lower strength ones would be fine

And here's a third. @cncnutz Are we going to see 2nm and 3mn stepper options from Masso with integrated brake (real soon)?

I'm considering a timeframe for replacing every 1.2nm motor with 3mn (and all the wiring) on the 1F Elite as it stands.

Nevermind. The correct way to address Z-drop isn't with a brake, but with counter-balance, to reduce or eliminate mass load from the Z stepper. And that's now taken care of here.

Pulling the trigger on new steppers, new wiring and new power supplies, shipping from AU too expensive, so shopping and making my own suitable parts. There won't be so much as a single resistor or length of wire on this machine from Onefinity.

Here's the Onefinity version. Pretty much plug and play, no extra wiring or anything else. Maybe a 5-minute job.

Except you're left with a 1.2nm motor that's still going to struggle with the spindle's mass.
