Hello I'm Ben and a complete beginner.

I thought I'd challenge myself by getting a Heavymill but now realising I'm a bit out of my depth. I have a few issues and any help will be much appreciated as I can't find my exact issue after trawling through the forum and help videos.
  1. The Heavymill has 2 motors for the y axis. In F1 I've only got x, y and z axis for the other motors so I'm assuming I need a 4th to run the 2nd y motor backwards?
  2. I'm trying to home x and z and have watched the videos several times but something keeps going wrong. I've pulled the spindle to front left and tried it both with setting the correct soft limits and -3000/+3000. All Axis should be 0 but after moving it with commands and manually the figures are way out and now I'm getting the alarm too, see pic. I managed to change all the numbers to zero by holding down the jog button for 3 seconds a couple times but now it just keeps moving z up despite the numbers on the screen not changing. What am I missing?
  3. When moving x and z the number typed in doesn't correspond to the amount of actual mm they move. I think I had x setup at 1 point but I've lost it and can't get it back.
  4. I've wired in an Invertek VFD and added the settings according to the instructions. Though when pressing go on it nothing happens. Is there something on Masso that needs setting before turning it on?
  5. Can I use hard limit switches for homing sensors too?

Many thanks

Ben

Hi Ben,

Welcome to Masso. I hope you enjoy the adventure.

The Heavymill has 2 motors for the y axis. In F1 I've only got x, y and z axis for the other motors so I'm assuming I need a 4th to run the 2nd y motor backwards?
For dual Y axis there are many options to achieve what you want. You can connect both Y axis drives to the Y axis output on Masso. If you need one to turn on the opposite direction you can reverse the D+ & D- on the drive if you are connecting your drives in differential mode. If you are connecting your drives in Common ground mode then you can connect one to D+ and the other to D- and they will run in opposite directions. You can also connect them both the same and reverse the polarity of one of the stepper motor phases and that motor will spin backwards.
If you want to have auto squaring then you need to slave the Y axis for which you will need the 5 axis version of Masso as only the B axis can be slaved to the Y

I'm not familiar enough to tell you how to wire it without you supplying a whole lot of additional information however there are a few members here who have done it and will be able to offer the advise you need.
This video explains the different Masso options

This video will take you through setting up homing step by step.




When moving x and z the number typed in doesn't correspond to the amount of actual mm they move. I think I had x setup at 1 point but I've lost it and can't get it back.
You need to calibrate the axis to get them to move the correct distance.

Did you issue a speed command to to Masso as simply turning on the VFD will not make it move if you haven't told it how fast. S10000




Can I use hard limit switches for homing sensors too?
Hard limits and homing sensors use the same switches on Masso.




Don't be overwhelmed by the task ahead. Take it one step at a time and you will get there.
Don't Rush as it is the quickest way to move slowly that I know.

Hi Ben,

I've built the Heavy Mill and got it working beautifully.

Peter has given you good tips, work through them slowly and you will get there.

Regards,

Arie.

Thanks Peter,

The Heavymill has a Gecko G540 drive which the steppers are wired into using instructions from 3DTek, but like you say I need a 5 axis version to be able to control the B axis so will ask 3DTek what the deal is. That being said I think the motor is bust as there's no noise when everything is turned on and still no luck when plugged into another outlet, or any noise coming from a working motor when connected to A on the Gecko :(

I managed to get it homing correctly. I was panicking before and stopping it early because the xyz distances were all random. I now know this is because the machine doesn't know where it is and resets to 0mm once homing is complete. Also to be able to set xyz to 0mm in F3 screen, the F1> homing > sequence boxes all need to be unchecked :)

Schoolboy error when trying to calibrate the 1st time and miss interpreting the word 'measure', thinking it meant 'read the screen' not actually get off my a** and use a tape measure.

Still not sure about the VFD. Arie do you have the Invertek and can offer some advice please?

I got the limit switches set for homing on x and z but need to fix the other motor before setting y.

Cheers.

Ben Harper sells the MASSO controller as a 3 axis and wires the "A" axis in parallel with the Y axis with one phase (field) reversed to rotate the motor in the reverse direction. If you want to the auto squaring function of MASSO you need to purchase 5 axis licence from Masso.

How do you have the A axis connected to the Y axis?

Once I know that I can provide some testing ideas. Gecko is quite robust and it is not likely that you have damaged anything.

I'm at the shed at the moment and have the changes that I made the Invertek here.
  • P01 = 30000
  • P02 = 4000
  • P08 = 10
  • P09 = 400
  • P10 = 24000
  • P11 = 2.5
  • P14 = 201 - To allow access to extended parameters
  • P17 = 16
  • P20 = 300
  • P21 = 1500
  • P22 = 2400
  • P23 = 24000
  • P51 = 1 - Sets VFD to accept MASSO speed control signal
  • P55 = 1.57 - You need to measure between all three phases and use average value.
  • P56 = 80
  • P57 = 8

Have you followed Peter's video on connecting VFD?

Regards,

Arie.
