I doubt that it matters. Imho. The important thing is that the pulse is crisp, clean, has a fast edge. And no variable fuzziness over speed. -- -hanermo (cnc designs)

'Problem' is it's only 90 or so slots ... think both machines are different, but around 1 degree step size ...

But I don't like Mach4 - already ruled that out! I'd stick with Mach3 but it's not a long term option although I'm more than happy to use it for another 10 years on the W2k computer that is running my

If you already have an encoder for index pulse, or tracking, you are all set.

They seem to recommend a resolution of 2000-10000 cycles per rev so yes, if you have a low resolution encoder you might be better off changing that to a "better" encoder. You could always ask them if

Yes You are missing something. Suggest the pokeys. Suggest the mach4 - even though I have not yet moved my lathe to it. And very much suggest rigging an optical encoder (cheap, timing belts + 2

Have you looked at the Acorn board from Centroid? <http://www.centroidcnc.com//centroid_diy/centroid_diy_cnc.html> $265 with the free (and limited) version of the software, add $99 for the next step

Not sure where is the bast place to ask as most of the lists I frequent for CNC are specific to a single option. I've got an Orac and a Compact8 Lathe both of which are running nicely from the Mach3

Hi to all. Checkout my new video at: https://youtu.be/yoGwjAB3Vpw https://youtu.be/yoGwjAB3Vpw Cheers Bob Adams

It might pay to keep a close eye on vibration. I'm minded of a 12 year old 1972 CB350-K Honda motorcycle I once had. It had quick connectors everywhere, that were allways inconveneniently vibrating

Hi All, Just a quick announcement of the GC-12, a new solderless DB9 breakout board that provides an easy way to connect a stepper motor to the G540 without

Hello, I looking for someone in LA or Orange county California to help design and manufacturer a set of Z axis/Quill brackets for a linear scale. I will be offering them as part of my 3

Hi to All! I use Estlcam to create the G-code for my machine controller. I also use my Shapes Plus program to create the DXF file to import into Estlcam. I recently seen a YouTube video from Estlcam,

Charlie, I'm on the left coast about an hour north of San Francisco so a visit is out. I imagine that the original Chinese control board would work with LinuxCNC. It would be a matter of figuring out

If you want to know about LinuxCNC, get on their web site at linuxcnc.org and browse the forums. There is a LOT of info there, and lots of people willing to help. Also, they have a Wiki with helpful

USB may be your problem. I don't think LinuxCNC will work with it. All the USB drivers I have seen are for Mach3. You may find more help on the LinuxCNC forum: https://forum.linuxcnc.org/

Hi Charlie: I have never used LinuxCNC, and though I am sure I could figure things out if I was physically there with the machine, I think I would not be of much use on the phone. I’m in Eastern
