Probably your connectors. Even if they are super tight, there can be intermittent connections.
physical vibration as a cause points to loose wiring or perhaps faulty mechanical switches.
Is your feed rate constant? (i.e. what's the feed rate in your GCode file). Doubt it's GRBL doing it. Looks like binding. Check your rails and...
I can't tell from the picture but it doesn't look like that chip is a mega2560 and knowing how cheap these Chinese controllers are, it's probably...
Is this a recent change? I had to 3D print a shim for my DW611 in the CBeam spindle holder. As I recall, I needed about 2mm thickness on my shim....
That message, "low memory...", is due to GRBL being at the limit of what the Atmel chip can handle. You could drop some features (like door, mist...
What is your feed rate (Fxxxx in the GCode)? I would use F-Engrave to do lettering but each to his own. I agree that multiple hours for a few...
We aren't mind readers so some information would allow us to help help you. What machine? What CAD/CAM SW. What bits? What are your tool paths,...
I have not seen that error before but am not familiar with UGS. Maybe some one else has an idea what it means. Maybe a bad install of GRBL - it...
OK, GRBL is a piece of software that runs on an Arduino. The Arduino becomes a CNC motion controllers when it has GRBL installed. You have to...
OK, that helps. You don't show the power supply but let's assume that's ok. GRBL expects a complete system. If your wiring is correct it may be...
dude, post a picture that shows how it's wired up. post the brand of shield (and a picture). do you have power for steppers? have you wired the...
Are you connecting your stepper motor directly to the Arduino Uno? What is this GRBL board you are talking about? Post a picture. Part of our...
I'll never, ever complain about my shop again. Scouts Honor.
Some good suggestions. I'd also suggest putting ferrites on your USB cable since you're seeing a lot of noise on the console of your sender....
The goal is to collect the dust, not spray it all over the place. The router bypass is part of an overall Dust Collection scheme.
A quick follow up on this. I got the pendant that Rob suggested and have it hooked up to a Teensy. Got all the switches and encoder working....
That's a creative idea. The only problem I see is that UV won't kill where there are shadows. I like the automated spray idea - no touch. Since...
Yes, agree that's worth doing. Did you disconnect them at the switches or the BB? I'd also take a close look at both sides of the BB circuit...
Yeah, pre-load on the screw is a bit of a muddle with all the force being on that little grub screw mashed against a threaded rod. Though, it...
