Building a 600x600 MPCNC: Good settings to start with?
-
starting points
- acceleration 100
- jerk 10
- max XYZ move speed 20mm/sec
then you increase them one by one .. start by increasing move speed then acceleration, I suggest you leave jerk at 10 (or even lower)

printNC
Low cost, High-Performance Steel Ball Screw & Linear Rail CNC
I think that places it in a whole other leauge than MPCNC.
In any case as long as the users expectations match the capabilities of the machine then it'll be fine. It just seems like OP might expect more than MPCNC can deliver.
-
@bearer how is linear rails and ballscrew "low price"
-
@arhi fair point, it wasn't my words - it was from the printNC web site. But I guess its all relative if compared to an industrial machine.

yeah, I got the "italic" as a quote
relative
you can get cnc machine (all metal, no printed parts) for 100$ these days assembled and ready to attach to usb and run so it's classic BS marketing made by them
...I'd rather purchase plans for miranda's machine
... it's imo much better than mpcnc + he's a totally cool guy that accept critique ... iirc Tomas gave mpcnc a finger and gave up on the project (and he was prepared to invest a lot of time in improving it and sharing that improvements) due to reactions of the original designer https://youtu.be/68ohaPYyiDA -
I wanted something stable that I could reliably machine aluminium with.
When I'm done, I'll still have spent less than I have on my toolchanger.So far, I've built the bench for it, ordered the steel and ordered the main kit of parts from AliExpress.

@jay_s_uk the printnc looks nice. If I am unhappy with the MPCNC build, I maybe will replace it with one
I just wanted to go fast into milling and had a spare board and pipes and a few printers. -
@jay_s_uk can you make a review of the printnc when you are done?
-
@dgrat yea, no problem.
I should be starting my build next week so I'll write some blog posts while I'm at it. -
@jay_s_uk I think this cnc looks like a nice project for a Duet 3. But there are not so many people around which did some tests.
-
I build a MPCNC last year. It took me just two weeks to give up a replace it with a Workbee.
-
@dgrat I have a duet 3 but its being used on my toolchanger.
I plan to use either a duet 2 or SKR (running the LPC port of RRF) with external drivers -
@dgrat the CNC build Iām working on now is based on a Duet3. Pretty excited to start making chips!
