Spindle Not Operating

[robb]

I have a MASSO G3 with latest update (3.44) installed. MASSO runs the spindle via a VFD. Today I tried to run a program to carve a 3D project. The axis all work fine but the spindle didn't turn and broke an EM. I checked through the VFD config (all okay). Cabling is fine. Using the command interface I entered M03. The spindle barely turned and, in the wrong direction. Should be CW for M03. I entered M04 but, no movement from the spindle at all. I checked the Spindle settings in F1 and all looks as it was last time I successfully used the CNC.

MASSO controls the VFD so, I figure it might be a MASSO problem of some kind. I'm excluding any problems with the spindle as it is only 3 months old and was working perfectly a few days ago. I have rebooted the system a couple of times.

Anyone had a similar glitch and have a brilliant solution?

Hi Robb

When you issued the M3 command in MDI did you precede it with a speed command eg S10000 then M03

Without the Speed command the spindle will barely turn and behave as you describe.

Yes, you're right of course. A bit remiss of me. I entered the command M03 S12000. I was looking at the machine a few minutes ago and I noticed that the gcode has, at line 8 the command S12000. When I run 'Jump to line 8' the machine runs but, the spindle is static. If I run the same instruction and press the Spindle CW button, the spindle powers up perfectly. I attach the actual gcode. Please have a look and tell me if you see any reason why the code is not powering up the spindle. usually, when I hit F2 and CTL+R, then CTL+S the spindle is the first thing to activate as the machine moves to X 0 and Y 0 and then plunges the spindle into the work. In its current state, I can run the job and X and Y axis work fine, as does Z axis but the spindle is static so I have to hit the E-stop toot-sweet.

ChaChing! Just had a thought. I had to re-install my OS and I am sure that I haven't replaced the correct Post Processor. I'll go and do that right now and let you know the outcome.

Hi Robb

If you have a look at your Gcode you will see on line 8 you have S12000 to set speed but you don't have an M3 so the spindle is not turned on.

It will not end well.

Yep, as I thought. I forgot all about the PP when I reinstalled the V-Carve Pro app. I didn't notice it was not there and so I was saving the files to an erroneous PP. My fault and I apologise for wasting your time. Job is now running and I have four panels to complete before the morning to keep my customer happy.
