I am starting the printing now. What kind of precision can we expect? Has anyone measured? My old mydiycnc monster machine is terrible, way to much slop.October 15, 2015 at 6:06 am #3527
Shouldn’t be any different that most 3d printers. Mine is in constant use printing plastic parts for sale in the shop.October 15, 2015 at 6:26 am #3531
Thanks for getting back to me, and thank you so much for the mpcnc.
I was actually thinking more about cnc uses.
My current machine is a diy minster that I’ve been trying to get up to snuff to work reliable. Mine has wiggle at the endmill thanks to problems all over. It’s cut size is only 30″ x14″ but its based on a terrible kit called mydiycnc. I replaced so much and dumped so much cash into it.
Have you measured tolerances? Whats an idea of plunge rates or inchs per minute for feedrate?

I have not found a way to measure the tolerances well.
The hardest part for most people will probably just getting the machine really square. This cnc I made has blown away the expectations I had for it, so I have not pushed it too its limits yet, in speed or precision.
Best I can say is you should have zero worries about tolerances in wood. Metal is where things start to change. In metal the expected tolerances increase dramatically. Not that they can not be obtained, you just need a good understanding of machining to get there. Not necessarily having to even do with the mpcnc.October 15, 2015 at 6:42 am #3535
As for the plunge rates, I am still out of state. I can check what I use when I get home. It is pretty slow, this where a realnlead screw could help. Speed of the z axis. To me they are not worth the money.October 15, 2015 at 7:47 am #3536
OK thanks. I do only wood so far.
Any info helps. Especially feedratesOctober 15, 2015 at 7:50 am #3537
All my videos have feedrates, just not plunge rates.October 15, 2015 at 7:57 am #3538
Oh OK I’ll have to watch them. My current machine is limited to 15″/min. Not sure if that’s fast or slow lol.October 16, 2015 at 8:24 am #3552
I just finished my machine and I am TRULY impressed with the quality. I cut a rather complicated logo recently and used a 1/32″ endmill and it required three passes to get the depth I desired. I used this as a test to see how well it tracked in the same path and I can not see any “layers” in the cuts from the multiple passes.October 16, 2015 at 10:07 am #3555
Good to hear clocey. Can we see pics or video?October 16, 2015 at 11:00 am #3556
That sounds awesome! Such a tiny bit, any inconsistencies should have shown up or broken the bit. Sounds like you have a solid build for sure.
Lets see it.October 16, 2015 at 6:43 pm #3567
I hope they turned out

oh yeah thats repeatability right there.
