move and jog erratic after upgrading software need help

[Marc F. Lupien]

My desktop is moving and jogging in a very strange (uneven) fashion - the only thing I can think of is the software...

I haven't been using the CNC for a few months but back in April, i downloaded and installed shopbot control software 3.8.4 - they say it was a major upgrade. I updated my computer but since I was non connected to the CNC, I did not run it.

Today, I run the software and went through the control box firmware upgrade and all that. When I tried a few Move and Jog it moved very strangely, uneven and Noisy - someting's wrong. I went to the shopbot website and found the 3.8.6 update, so I tried it... more of the same.

The weird thing is : it moves fine with the [SK] dialog (from the keyboard) but move and jog are not working right.

I uninstalled everything and reinstalled all, same behaviour.

Anyone got any idea ?

Try 3.8.6 Marc and it will probably come back to life.

And remember to update the firmware again.

Thank you Bob and Jerry,

But I already upgraded to 3.8.6 and reloaded the firmware just incase. I am french canadian so my message might not have been so clear...

Today I will try to completely cut power to my CNC to make sure it resets and reload the firmware and retry to see what it will do. I must say I am kind of lost.

For the rest of the community...

I have down graded Shopbot control software to version 3.8.46 (and reloaded the controlbox firmware for that version) and everything is back to normal.

This would rules out CNC problem and almost rules out problem with my computer itself (fairly powerful and stable).

I have brought my problem with the tech support at shopbottools and here is the situation for now: they are aware of controlbox firmware issues with some users and they are working on it. For now I will keep the older software and finish my current project.

They suggested maybe I could try installing the beta 3.8.7, update firmware, then reinstalling 3.8.6 without installing firmware - in other words : using shopbot 3.8.6 with the firmware from the beta 3.8.7 to see what happens.

Thanks you all for your support. The forum contribution is greatly appreciated.

If you haven't used it in months, you COULD have gotten a bad connection on your motors through corrosion, or something. You could also have gotten a power spike that took out a driver. You should also check your power connections in and your ground connections for the machine. I am sure there are a number of other explanations.

I would shut the whole thing down. Check all your connections and maybe even check the connections to the board for the drivers.... see if that clears it up...

Best of luck to you.
