I am getting a severe rash of these now on every cutting job that has some time in it. Very frustrating to restart multiple times! I have to think my GRBL board has become defective in someway. Last job I did with VERY easycut depths and speeds. Should have been minimal effort on the router. Dewalt router set down to 4.5 speed.
I was milling Maple taking 0.05 depth cuts at 40 in/min, 15 down.
Just got the board in the mail today. On opening it up, what is the thermal paste for? Also, my first board was white, and this one is black. Not that I care about the color, but is ta a problem?
Thanks
EDIT: Disregard. I see now. Also my original board is the same color.
With what you’ve documented, it sounds like a super-noisy Makita router… I’d grab your longest extension cord and run a different phase outlet from somewhere to see if a more isolated router power source will mitigate your issue, You’ve got the latest/greatest CM controller and that’s got the latest noise suppression support.
I know you have tried many things but have you tried a different usb cable?
(edit) i see you did replace the usb cable a few days back…only other thing comes to mind is what will was saying about the brushes,motor could have collected somthing in the brushes,may be worth cleaning or replacing
What Mark said - With the Makita AC source moved to that extreme I’d say it’s some other noise ingress locally… It’s corrupting your USB controller/hardware based on your port related error dialog.
I’m using a USB isolator into a 4-port hub connected to 2 CM controllers. I also have ferrite cores on all wiring to the controllers.
I really hope I don’t have to go that route. I’ve already sunk about 2 grand into this thing all together and I’m out of cash and haven’t really gotten it working right yet since unboxing. I can’t really afford to keep throwing money at it.
Copy Will. I have a support ticket in and I sent a summary update after trying the new board. I hope to hear back tomorrow. Unfortunately I don’t have another router to try. I ordered this machine on Thanksgiving as the package deal with the makkita router. My other router is a full size rigid so no dice there.
I may have to order a makkita from home Depot or something. If it fixes it, I’ll return the other in the box. No shame there. This thing is like brand new. I don’t want to switch to the DeWalt because I got the eclair collets for the makkita.
I have had “serial errors” errors with my Makita as well (I have the 230V version though). I bought it some weeks ago as an alternative to the Dewalt due to its lower RPM range, and the Dewalt never had this problem. Tried different things, but what seemed to solve the problem was connecting the Shapeoko and the laptop to a UPS (uninteruptable power supply) while keeping the Makita connected directly to the wall outlet. The UPS effectively keeps any noise on the HV circuit from reaching the controller/laptop through its inverter (at least the “online” kind which I use). Maybe worth trying…
I think we are fixed now. Now more disconnects since adding the usb filter. I only finished the job and haven been able to get much time on it since due to work and sick kids/wife. I plan to try and cut some more tomorrow.
Definitely ground that spiral wire in the vacuum hose. I used one without a ground cleaning old insulation out of an attic and got a shock that was as bad as one coming from an electrical outlet. Better safe than sorry!!
