Just curious do all of you use laptops or something with your CNC?
I had planned on just using gcode and putting the SD in and running it.
The biggest problem I have is that when I move the axis around i have to power off the machine to 0 the axis again (without a gcode command available).
Of course that means to start the cut it moves back to 0 0 0 .
Im sure I could do it off of an ipadā¦ Is there any control software with Ipads that would allow me to enter gcode commands and move axis etc?
thanks
I have a raspberry pi mounted to the wall above my workbench as a shop computer. Then I have another raspberry pi attached to the rambo running the v1pi image and cncjs. Cncjs controls the cnc, I control cncjs via wifi and a web browser from my shop computer.
Im sure it works well, just seems a bit more than I need :)ā¦
I have a chromebook laying around down there too, right now I use it for my duet wifi based 3d printerā¦ but i could use it for this too, if repetier or something had a chrome os app haha.
Oh sorry, I thought you were asking for our setups. I understand where youāre coming from. Iāve never tried to run my machine from just an sd card an couldnāt imagine not being able issue my own gcode commands.
I did a quick google search and didnāt find any gcode sending apps for ipad or chromebook. You could use just one rpi, not two like Iām using. If youāre handy with electronics you could make a pendant.
On the MPCNC, I just us the LCD and gcode files on the SD card.
Technically, if you want to do custom Gcode commands, you could just have a couple of gcode files on the SD card with the typical commands you want to run. Load the file and tell it to āprintā and the file would run like a macro.
On the Laser Engraver running GRBL, I have a Raspberry Pi running cnc.js. Then I connect to it from the shop laptop to load and run everything.
Iām still in the ācontemplatingā stage of adding another Pi to the MPCNC to run cnc.js. Iāve been running it since 2017 without one, so not sure why I feel the need to add one now.
However After the cut, the X axis just started moving back to the Left, and WAYYYYY past its zero.
I have this in estlcam as the post code
G28
G92 Z20
It should just go back to 0 and raise up the Z to get it out of the way. It went WAYYYY past zero. i had to panic and pull the plug, which didnt stop the endmill and it drove in to my table haha.
If youāre running Marlin and have the LCD connected, go to Custom Commands, there is a āReset all Coordinatesā entry that will set the current coordinates to (0, 0, 0). I think that does what youāre looking forā¦
