MPCNC DIY Build

So whats the advantage of running it over parallel?

Since I have the rambo, I’m gonna have to use mach4, not sure if this converts usb to parallel, seems the other way around.

there is no reason to ocnvert something to parallel. and there is no advantages. Is just becasue mach3 was made to talk to parallel port, that’s it. So when parallel port disappearded, someone ended up making a converter to USB or Ethernet called smoothstepper. They are basically plug and play, 5 minutes installation and works perfectly. Anyhow parallel port control board cost like 10$ in case you have an old pc :grin:
Mach3 is still used because there is so much information available. Allows you to do everything. Except linux CNC there is nothing free or close to price that can do more and better. Still the cheaper cncc software you can have.

Yeah, I’ve decided not to go with the Rambo. It really is just an all in one board anyway, for added cost. I’m going Ramps with DRV8825 drivers and the recommended NEMA 17 motors. If you could suggest what high torque NEMA 17s to go with and what external drivers (I assume you mean something like DM825?). I need to try a few different workflows. I was looking at running off the SD card like I would a 3D printer. I’ve got Fusion 360 and will try ESTLcam or Easel as well.

I already posted the list some time ago. MPCNC DIY Build. Check the N of the suggested nema. the higher the better. The one Iisted are not bad, also compare to the price.
You can use whatever you want to send the gcode that’s not a big deal. I personally started with the USB but got tired of the process every time a small adjustment was needed. So now I have a common folder shared between the PCs and drop there the gcode to be run on the CNC PC. Much faster.

I love his voice over.

I’ve been watching a bunch of CNC videos…it’s so satisfying!

that spindle is insane, just the bearings and build of that thing is just so good.

Marco reps upload? Oh and he’s actually finishing a project!

That is a wonderful day

Any updates on the build man? I’ve nearly finished printing and have just spent some time learning ESTLcam and how it links with Repetier Host.

I gotta figure out how I’m going to mount the end stops. I thought I bought the right ones for the mounts I printed but they don’t line up correctly.

Wiring is about halfway done, everything is routed to where the board is going to be mounted.

But the whole point of me getting the more expensive board was to be able to use dual endstops!!

I may have to model/change the STL of these endstop mounts

Congrats. Did you just make it?

It’s been a long time coming. Started working on this August last year. Spent forever figuring out what firmware to use with a skr 1.3. Almost no firmwares support tmc2130 stepper drivers, simultaneous 5 axis, and the lpc1768 chip in the skr. Ended up using smoothieware with some modifications to support software spi.

Yeh can imagine. How you will be happy with it

I’m almost done with my OpenBuilds WorkBee CNC controlled by centroid acorn, I find the centroid software much simpler than mach3

Ah nice I always look at the workbee. For the price great kit.
Most of the software are easier than mach3 :sweat_smile: In my case Ian just use to it. It’s old but does so much stuffs and with all the macros available I find it complete

You guys, stop being so productive on my thread, you’re really making me look bad.

All that I have left is the wiring and the endstops.

The printable mounts for the endstops I got don’t fit so I need to track down a solution for that

Yeh you need to catch up :joy:
Why not design another one for the limit switch?

I’ve been thinking I may have to do that. It would be good practice for me!

I just haven’t had any time to spare lately. I just interviewed for my “dream job” at work, had to spend a good amount of time studying and preparing for that lately.

Hell if I get it, I may not even finish this project, I’ll use my bonus to just buy one! @ducktaperules has got me dreaming over the new larger workbee, it’s all lead screw now and under $2k and the size I need!

yeh workbee is really good for the price. If tollerance is not a big deal is the way to go. Then from there upgrade to linear rail and ballscrew is just matter of time :grin:
Good luck with the job!
