Dave, Thanks for the photos. My milling machine should be delivered in the next couple of hours. I may be able to attach a timing pulley to the top of drive pulley. It will require a large pulley so I can bore a hole that will allow for the drawbar and mounting screws to attach the encoder pulley to...

Thanks Marty, I modified a pulley for the lathe spindle by boring it out to 30mm and then broaching a keyway in it. But the mill (PM25MV that will be delivered today) does not appear to have room or a mounting location because of the drawbar (at least by looking at the pictures). Was hoping that som...

Brian, I don't have a durapulse drive, but I look into them while setting up/testing my AC Tech VFD. So this may or may not help. The area that gave me a few headaches was setting the parameters on the drive (chapter #4 for your VFD manual). You must set parameters for the inputs on the VFD, for ins...

Thanks for all that helped.

I ordered an encoder from Automation Direct (INCREMENTAL, DIFFERENTIAL/LINE DRIVER OUTPUT ONLY, +5VDC input, 2500 ppr).

Still looking for an answer to this question: Does anyone know of a mount for the PM25MV mill?

Thanks,
Chuck

I have read through a lot of topics on encoders, but could not find what I was looking for. My question is what are the requirements for an encoder that is to be used with an Acorn board? I have a omron E6B2-CWZ6C (NPN open-collector output and 5-24 vdc). I have on order a omron E2B2-CWZ1X ( Line-dr...

Marty, your video did help. I ended up wiring in several switch to the vfd to allow me to test it. Unfortunately the testing took a while to do, the default password had been changed (1000 possible choices), after 128 tries I found out what it had been changed too. The first thing I did was to remov...

Thanks Marty,

I am waiting for a few more items to be delivered so I can layout the control panel. Then I can start testing as I build it.

Thanks for the information and for all of the video that you have made. I had planned to use the relay board based on the schematic that you linked. And have looked at the other drawings that use other brands of vfd's. I don't expect to have problems, but plan to test my vfd driving the spindle usin...

I purchased a used Techno CNC Lathe. I'am scrapping the current servos and control board and replacing them with an Acorn board and Clearpath SDSK servos. It currently has an AC Tech SF110S VFD installed that I think is good. I have not attempted to connect it to the Acorn board yet. Does anyone els...
