Re: Acorn and CPU Specs?

Success! Everything working great. Smoothing really helped. Cuts to 100ipm are smooth and fast enough for my hobby needs. Thanks again guys.

Re: Opinion wanted on z-axis

check out http://www.automation-overstock.com/ for rails and ballscrew.
and https://www.industrialmetalsales.com for aluminum flat bar

You can build a z axis that is engineered by you to fit exactly what you need.

Re: Acorn and CPU Specs?

Thank you to all who responded to this post. I built a new computer and currently testing. So far, able to cut at 50ipm without problem. No errors. I tweaked the deadstop and delta setting a bit to prevent banging with direction change that I think was contributing to the problems. Mine defaulted to...

From My previous post: Machine basics: Roughly 24x48in Ballscrew direct drive 5mm pitch on all XYZ. Dual driven on Y. Software pairing. HiWin and generic rails. 2.2kW VFD and 3.5kW spindle (automationtech just kinda sends you whatever they have in stock but in each case they sent an more expensive p...

Re: Acorn and CPU Specs?

Thanks again for the input. Machine Overview.jpg Control Box.jpg Z axis.jpg This was the first part cut at 50ipm. No errors. Wood Part OK.jpg Revised the part a bit and recut at 60ipm. Everything is good until the last 2 passes and you can see how it moved the outside profile out about 0.0625in Wood...

Re: Acorn and CPU Specs?

Thank you all for your responses. I already have a new PC on order and should have it built up with clean Win 10 install this week. It should far exceed the specs and has NVMe SSD as well. I have run several more tests with spindle off and can hear when things stop running smoothly. There are no fau...

Acorn and CPU Specs?

What happens if the CPU doesn't meet specified single thread speed mark of 1500? Are their any hallmark behaviors to look for? My HP all in one only scores 1200 on the CPU PassMark list and I would like to blame it for random errors. This is what happens...I can cut a part out perfectly then on a se...

Re: Keling KL-5056D to Acorn

Just want to pitch in since you are using AutomationTech drivers. I have found on my current build with KL8060E's that the 5v logic can cause some headaches. And here is a suggestion to all using these type drivers. The 5v logic needs to share the common with Acorn board/PS. I believe the reason tha...

Axis Pairing and Squaring

Does anyone have the axis pairing and squaring guide for CNC12 4.12? I found a great guide for 4.14: http://www.centroidcnc.com/centroid_diy/downloads/acorn_documentation/paired_axes_acorn_user_guide.pdf Unfortunately, this is for 4.14 which hasn't been released. I need the instructions for 4.12 bec...
