Re: Another rebuild

AN update, so far I have the gantry frame built, ready for the Z and X rails to be fitted, also have the X Z base plate built with bearings and the spindle bracket. Probably will not get back to it until after Easter. Hoping that Bertus has made progress on the 5 axis board. :D Slowly but surely......

Re: Power supply for Pi Hat

Hi All, New to Pi Hat, so hoping someone might help me. I have Neam23 drivers with 48v power supply. Pi Hat can accept 12-36v. Pi Hat requires power in order for arduino chip to be powered. So do I need stepdown converter for 48v to be down to 12/24v? Or is there another around that? Thank you, XDe...

Just signed up to say that I found this problem, but you've beaten me to it.

You say you're removing the connector? Are the leaving the pads in place on the PCB so a user can still add their own? It's very handy having access to external i2c devices.
Yes... the pads are still in place.

Re: This problem, would it be hardware, software or firmware???

Have you tried another G-Code sender? UGS....

I think I have seen someone mention this issue on another site related to lasers.

Not saying it's not worth $90, mine is excellent and I would have paid more.

This just made me laugh.

Re: GPIO Triggered by Unknown Program on image

Bertus, what goes into the serial tuning? Is this something that was already done on the board or something that has to be done? This is the current script to enable hardware serial on RPi 3's and up... https://github.com/Protoneer/RPI-CNC-Config-Scripts/blob/master/scripts/_RPi34-Serial-Config.sh ...

Hey Guys, I'm in the process of rebuilding my CNC with a genuine Protoneer shield, but I need Analogue Output control for my spindle driver as its one of the DC controlled Chinese drivers, which is either set with a Pot or 0 to 10V analogue control if available (mine did not come with analogue cont...

I am working on a lift table driven by 4 identical steppers. Can I use shield v3.00 to drive all 4 steppers synchronously.
If you use your own Arduino code, definitely.

Re: LCD display via second Arduino

I've been wondering if it would be possible to implement an LCD display like this one. https://wiki.shapeoko.com/index.php/LCD_on_GRBL#Full_version_GRBL_1.1 Correct me if I'm wrong but it appears to piggyback on the existing serial connection and extract data by sniffing/listening to the $10 update...
