Hi all, hoping the team can help with something that's been frustrating me! I've been looking for a grbl software program that can do leveling. I tried a couple but without much luck. Candle looks good for conductive materials like PCBs. Mainly work with MDF so non conductive. I want to use my probe puck (19mm thick) with candle, any idea on how I can set it up so the true Z probing tacked off the 19mm of the puck? Hopefully I've explained my delemor. Any ideas? Cheers Dave
bCNC is really good for this, Candle is YEARS old and out of date. GitHub - vlachoudis/bCNC: GRBL CNC command sender, autoleveler and g-code editor for non conductive materials you can use a microswitch. This is my one, just a microswitch glued to a magnet (the silver disk) so I can stick it to the face of the collet. The yellow half ball is an airsoft pellet filed to about halfway. this make positioning of the probe a bit less critical since an ~equal radius from the switch lever is maintained as the lever moves. It could be built better, I threw this together to see if it would work, it does. Note that this connects to an optocoupler that feeds the controller. github.com/gnea/grbl under the limit switch section describes the why and how. Or you can use a 2K2 pullup resistor to the control pin and connect the switch between the pin and ground. Probably ok unless your VFD spindle is running.
Thanks for this. I'll have another look at bCNC , tried it a long time ago but can't remember why I didn't pursue it more.... Cheers Dave
