Re: V3 Board +grbl 1.1f

Isn't the v3 shield only compatible with GRBL 0.8 ?

Also pin 11 of the Arduino has an internal pullup resistor - this would be why the relay is always on.

Re: benbox freezes

You don't say what sort of controller you have, but I'm gonna hazard a guess that its not that reliable...

I would cut your losses and buy a Protoneer Arduino CNC shield for $20. Will solve all your problems - everything else should work as is. Direct swap.

Re: My Protoneer Setup

Looks great :)

I especially like your buck converter power supply mod. Looks pretty straight forward, but could you post a few more details. Connections etc :)

Thanks

I can download from both sites with no issues.

Lasergrbl is amazing! I threw an image in, saved the gcode and I'm streaming it to the cutter via the laserweb3 server on the rpi. Images look great. pwm looks great. And the software was free and super easy to use. So glad I got bored and decided to make a laser cutter!
You got my vote :)

Now I've got it at 1000 and I have to keep the laser moving at about 1000mm per second to keep the line nice and sharp while burning MDF. That or my steps per mm are way off, which is possible since i haven't checked that yet.
That is really fast. I suspect that is 1000 steps/mm.

Try LaserGRBL. It's completely free and generates the GCode depending on the settings you choose.
Greyscale, Solid or Outline Burning.

Great software but only works with Windows. You get my vote if you can get it going on a Pi :)

Re: ALARM Bells

Speed is the balancing act - as speed increases, torque decreases (as does accuracy). You can't really increase the speed except by decreasing the microsteps (or increasing voltage, but you are probably already at max) You can change the maximum rate ($110-$112) but they are probably already at max ...

Re: ALARM Bells

Normal behaviour (the first bit). When you change the microsteps, you also need to change the GRBL settings - steps/mm $100 - $102. If you go from 1/2 step (which I think you must have previously had) to 1/16 step, you need to multiply your steps/mm by a factor of 8 (you are now doing 16 microsteps ...

Re: ALARM Bells

I use 16 microstep for my CNC.

I've also found that small changes in the current (either increase or decrease) can significantly change the sound of the steppers.

I'm away from my setup for a few weeks, so I can only provide theoretical, not tried and trued, feedback - sorry - holidays are hell ;)
