In fact, flipping back and forth is no big deal either: just put reliable connectors on your wiring. If it isn’t what you want, or if you later “upgrade” to the MPCNC “standard approach” that should be no big deal. Remember that Marlin is based on GRBL (read the credits at the top) and DIY CNC machines predate 3D printers by a decade or so! My setup described above is basically “Path 3”. The micro-controller regenerates the isochronous timing required to control stepper motors. That’s what GCODE was all about: it’s a motion control language that enables a PC/laptop to send aynchronous commands to firmware running on a micro-controller.

GRBL is Arduino firmware designed to offload the PC from having to deal with the millisecond timing problem and eliminating the parallel port dependency. If you get super-serious about 6-axis metal milling it might be the only choice. However, IMO, that approach is ultimately a dead-end as the parallel port will inevitably become unavailable (note: most USB to parallel converters do NOT work because the required precise timing gets buffered-out.) If you like tower PCs with PCI slots and plug-in boards with parallel ports then maybe Mach is for you! I’ve never used it but the CNC world still seems to think it offers the most control options.

The host control people (Mach style) are devotes of the parallel port because it is the only way to do millisecond accurate timing directly from a desktop/tower PC.

You could use Mach3 (or similar) PC CAM software communicating with a CNC stepper controller (like this) over a legacy parallel port. I figured all those CNC DIYers must have some good stuff so why not try it? I actually got my MPCNC working with a RAMPS clone first and then decided to try another approach. I’m comfortable doing this as I built my own Prusa i3 using a RAMPS clone and later a RAMBo, but the prospect of setting all my parameters in the ESTLCAM GUI in meaningful CNC terms and units and having it configure and load the UNO was pretty attractive. The downside is a rather complex workflow and a high “fiddle factor” as you tweak and recompile the Marlin firmware and play with Repetier Host. If you want maximum flexibility, if you embrace the RepRap philosophy, or if you plan to do 3D printing (need extruders or heated beds) then the best path is as explained in the main instructions on this site. Path 1: ESLCAM + Arduino IDE + Marlin + Repetier Host
#Estlcam software driver
Not doing this will cause motor skipping, driver overheating, cooked motors, and/or other bad stuff.īased on my research so far there seem to be three paradigms for driving your MPCNC.
#Estlcam software drivers
Also, as with all stepper drivers (including RAMPS) be sure you tune each stepper’s (the tiny potentiometer) power level using the instructions here. I strongly suggest you get the basic UNO talking to your PC before you mount the CNC shield.

I got it working on XP and OSX after some fiddling. You may also have to load a driver to get the USB/serial connection going as it uses a less expensive driver chip than the FTDI part on official Arduino/Genuino boards. You will probably have to carefully straighten the pins before mounting the CNC shield. The Uno that comes with the $35 kit on eBay is a Chinese knock-off. If you carefully set the ESTLCAM work area size and simulate the tool run before going live you shouldn’t bump into the limits. My next move may be to use the six end-stop inputs on the Protoneer, but so far I’ve really not found much need. It won’t control AC motor speed but it does automatically turn my Makita on/off which is handy because the router’s toggle switch is inaccessible when installed facing the Z-axis in the Universal Mount.

I’m using a homemade plug box with a high quality solid state relay built-in that is toggled by the +5V output of the Protoneer.

Since this post I’ve started using the spindle enable feature of the Protoneer board and ESTLCAM’s GUI.
