Version: 3.49.07b (Beta Version)

[peter35]

I am using the following.

G2-2798 4 axis mill.

V3.49 has been working fine and had run 300 parts without a hitch, so all good.

Installed V3.49.07b 24/7/21.

All installed without a problem, checked F1 screens and no changes.

Home machine, ok.

Loaded and ran previous program, Machine went to correct co-ordinates, motor started and z axis went first position, all good.

Got to next line, Z axis down and feed reduction and machine locked up.

I could push on screen start button but nothing would happen,

pushing on screen spindle stop and this did stop spindle.

Other than spindle stop, no other buttons would work, rewind, start, F1-F6 would not work, these buttons did light up but nothing else.

This was all done with the mouse which was fine.

Keyboard did not work, F1-F6 did nothing, control M or E would do nothing, like the keyboard was dead.

I shutdown and restarted machine and it repeated all of the above.

Homed all good,

Ran same program and same result as above and stopped on the same line.

Program ran to line 16 N65 and then froze.

I have just gone back to previous version, all running as it should.

I would be more than happy to reinstall new version if you require more information.

Peter,

Can you supply your settings file, so we can test.

Regards,

Arie.

Arie

l will give a copy of current settings as well as 49.07b for comparison tomorrow .

Hi Peter,

I loaded V3.49.07b 4 axis into my G2 and run your Gcode file using my settings.
I gave it a run and it ran from start to finish no problem.
I then made a small change to the M30 command at the end of the file M30 L0 to make it rewind and run continuously.
More than 600 cycles later it is still running and has not stalled or frozen.

It would be worth providing a screen print of the F4 screen so that the G54 and Tool 6 settings can be replicated in testing as well as the settings and tool files.
Cheers
Peter

Hi Peter,

I just had a thought.
When you reload the new software please double check the General settings on the F1 screen. Please check that there is no tick in the Limit maximum feed rate box as the default feed rate for this is 0 and might cause the type of issue you have experienced.
Cheers Peter

G'day Arie & Peter

Have reinstalled v3.49.07b and have fixed issue with program stopping.

Peter, you were correct, general settings the default feedrate was ticked, cleared this and all good.

Upgrading from 3.49 to 3.49.07b, l had a change on feedrate over ride on general settings and l lost my fixed ip settings in wi fi.

Have downloaded latest masso link 2.1 and will play with this later.

Thanks for the update Peter, glad you got it working.
Hope you like the new version.

Cheers Peter

I am using the following.

G2-board 4 axis mill.

V3.49 has been working normally. I Installed V3.49.07b 25/7/21 and changed the feed on set up.

Once booted up the screen had a new line showing Gcodes: G00 G17 G90 and G94 on my setup.

I ran gcode that I ran under V3.49 and everything worked normally using the V3.49.07b and the stepper motors ran a little smoother.

I went to test F5 Conversational programing and it was blank. I use the Conversational and it would be a major loss especially for threading. If possible I wish to add more the Conversational programing such as circle drilling, making slots, engraving and a list of ten other functions.

To recap the V3.49.07b worked and no bugs found but to lose F5 Conversational programing is a trade down.

Thanks for reading. Jim

@redstonejim

Jim,

From the the release notes.

• ALL Mill tool changers now supported for Mill 4 & 5 axis version also. NOTE: Conversational wizards are now not available on Mill 4 & 5 axis versions.
  

We had to make a choice remove Conversational wizards or remove Tool changer logic, unfortunately for you Tool changers won.

Regards,

Arie.

Hi Jim,

The conversational wizards on mill 4 & 5 axis were removed to free up memory to allow for continued updates and new features. Those who want the wizards need to stay at 3.49. Unless I am mistaken the Mill wizards did not include threading. Lathe has a threading wizard but it still has them.

The line of Gcode at the bottom of the screen shows the current status of MASSO. Very useful if you stop a program part way through and leave the machine in incremental mode in the middle of a drill cycle. You can see at a glance what state the machine is in.

Hope this helps

Cheers Peter

I have a issue with conversational circular pockets...I put in 12.2mm diameter and its actually machining 18mm diameter...I am using a 10mm cutter...everything else is fine except for the diameter...any ideas?

 

[cncnutz]

I had a look and a play and found that if the tool diameter is larger than half the pocket diameter the final pocket size will be incorrect.
A 6mm cutter or smaller will make a 12.2mm pocket but a 7mm cutter will make a larger pocket.
This is true for both the G2 & G3

Further investigation revealed that the pocket algorithm does not allow a cutter to make a circular pocket smaller than 1.8 times the cutter diameter. I don't know if this is intentional or not and have created a ticket to get it looked at. If you bear this in mind then you will be use the wizard in it's current form if you use to a cutter half the diameter of the pocket.

Cheers Peter

Thanks Peter for the quick response and the reasons why...I just sent a email to support about it but I was hoping you would come back and let me know the issue. I dropped support a email literally 5 mins ago about it but you have answered the question. Now I know..as there is nothing in the documentation at all about it. I will use a 6mm cutter and that should solve it...thanks again. BTW love your videos keep them up. I am looking at getting a G3 now for a router I bought that I am rebuilding...thanks again

I believe, if intentional, it may be there to ensure a minimum degree of effective chip removal from the hole being milled.

There is an issue with "end mills", specifically 4 flutes that there is a little pip at the centre of the end mill that is not cut (side effect of how the cutting faces are ground. These end mills can not be vertically plunged but need to be ramped into the work (e.g. spiralled).

You may see something called a "slot drill" which has only 2 flutes which can be vertically plunged. The two flutes can be ground such that there is a cutting edge at the centre.

There are some 4 flute end mills which have non-uniform cutting edges such that one of the flutes has a longer bottom cutting edge that goes to the centre. This is a recent cutting edge grinding style but I don't have one on hand to show the difference.

A 4 flute end mill that can not be plunged, requires ramping:
