E-Stop not working

I have an S3 which I successfully built including the included cutoff switch. The switch disabled all motor activity when it was set to the off position and enabled motor activity in the on position, as expected. Later, I added limit switches and setup hard and soft limits in grbl. I also soldered t...

Spindle control

I am building an S3 with the Stepoko board. I want to be able to send a spindle on/off control signal off board to an external tool that I have mounted on the Z plate. I basically need a 5V signal, on or off. If it were something between 0 and 5V, like an interpolated value depending on the speed of...

Re: Setting limits

@twforeman: where did you get your limit switches from? Did you use the Carbide3D kit?

Re: Setting limits

@twforeman: Thanks for the response. Sorry, the $110 was a typo. The grbl version 0.9j that I'm running won't allow you to set $20=1 unless $22=1.

No. No limit switches, yet. They will be on order shortly.

Setting limits

I need to set limits to keep from banging my machine up against the ends and ripping up my belts. I used the following gcode settings but every time I try to move the head I get an alarm: $22=1 $20=1 $110=100 $130=400 $131=300 $132=30 Can anybody shed some light on how the limits can be imposed and ...

Re: How to reverse motor direction

OK, got this one figured out, too. The doc says $7 is the setting for inverting motor directions, but in actuality, the firmware says $3. I set $3=4 and everything is hunky-dory. Thanks.

Re: Motors hot at idle

Answers are inlined below: Stepper motors work their hardest when holding position -- that said, they shouldn't be that noisy (mine just kind of hum) and they shouldn't get that hot (they're bolted to metal plates which function as heat sinks). >> I would call it a kind of metallic-sounding hum. Not...

Motors hot at idle

On my new Shapeoko3, the X and Z axis motors are getting really hot at idle (too hot to touch and I can stand touching really hot things). At idle means all motors stopped, no G-code running. The motors emit a high-pitch "eeeeeeeeeeeeeeee" sound constantly. When I input movement codes, the motors al...

How to reverse motor direction

I want to get the GRBL to mirror motor direction in the x-axis. I thought $7=001 might do the trick, but I don't know how to set $7 in the Universal Gcode Sender software. Any help appreciated. Thanks.
