Joint 4 following errors after software update 5.8.1

Troubleshooting the Pocket NC
#1

Hi, after updating to 5.8.1 (or 5.8.2) (from 5.1.5) Im getting a lot of Joint 4 following errors on Fusion 360 rotary toolpaths. Im using latest Fusion 360 CAM postrprosessor with plugin. I have disabled G93 and G94 since those made more errors and my code looks like this

N74990 X-0.691 Y-1.757 Z2.234
N74995 G0 Z4.496
N75000 Z5.25
N75005 G53 G0 Z0.
(4_FLOW5 20)
N75010 G54 G0
N75015 G0 A0. B630.
N75020 M254 P9
N75025 G59.3 G0
N75030 G0 X-2.281 Y-7.214
N75035 Z5.25
N75040 G0 Z3.1
N75045 G1 Z-0.054 F1200.
N75050 X-2.242 Y-7.192 Z-0.135

It seems that on line N75015 every time I get error.
Previous 4th axis position is N61460 G0 A0. B720.

Please help urgently. Should i roll back to V5.1.5?

Machine is V2-50 CHK

What serial number is your machine? Could you attach your calibration data? You can access your calibration data by going to Config tab > Server tab > Machine Config panel. There’s a text box where you can enter a serial number and then click the Download button. Feel free to send this info to service@pentamachine.com if you would prefer not to post it here.

If the same G code program works on your previous version of Kinetic Control, I would revert and continue to use that until we can identify what is going on.

Hi, thanks for reply. Im getting error: uploading attachments is not allowed by new members. Also email rejected file attachment and getting google automatic attachment rejection messages from your server. Would you have some support system where I could upload the configs? EDIT: Sent a download link in email.

#5

Sorry about that, I’ve made you a basic user so you should be able to upload files now. Otherwise, I can check with service later today to get those files from you.

#6

I have your calibration files, and I’m not seeing anything out of the ordinary. Could you please include your G code program and any tool and work offsets that are in place on the machine?

#7

Thanks, Work offsets used were Y44.0 Tools offset for 1mm ball end mill TLO -84,76mm. The problem occurs only on one combination with toolpaths connected (repositioned with Z Tool orientation rotations). Im out of workshop for few weeks and have to get back on the issue later regarding gcode.

#8

Hi, I did more testing and it seems that old gcodes are not working (there is several issues related to toolpaths with B axis rotations with this update.
Could you help how to downgrade back to version 5.1.5? Can i use USB stick etc? I tested also the new versions after 5.8.1 → 5.8.2 and cannot do a reverse anymore from #/config/server (it shows only deploy 5.8.1 after I shutdown services)

#9

I’m away from my computer right now, so I’m unable to get you back to v5.1.5 until Wednesday. These commands should get you back to v5.5.12 (see this page https://pentamachine.atlassian.net/wiki/spaces/KCUR/pages/581074945/Kinetic+Control+Software+Versions):

sudo systemctl stop PocketNC
sudo ostree pull kinetic 6e965ed2a4080300ed593eda7ec0993fd0fe55a7e12003278841aec0137bbce0
sudo ostree admin deploy --os=kinetic 6e965ed2a4080300ed593eda7ec0993fd0fe55a7e12003278841aec0137bbce0
sudo reboot​

In an effort to fix these issues, though, can you share your G code that isn’t working on the latest version?
