thanks for sharing so much of your development. I was interested in the last one, but the use of daughter board makes this one a no brainer. Two questions:

1. Did I read right that you're still...

Sounds like this is shaping up nicely. Also funny as I maintain the TFS project for a large NC software development team, and given the choice, I'd probably go that route, but since it's not free, I...

I've seen some complaints about the execution speed for arduino code, so you're right, there's likely portions of the code that would need to be written in the lower level language. It would be nice...

First, I wanted to say congratulations on a fantastic project so far. You've accomplished a huge amount in a very short period of time.

I wanted to touch on a couple of things that have been...

This sort of device exists in several incarnations depending on the industry segment utilizing it. I've seen it referenced both as a cell controller and a factory controller. You are correct that G...

Got a little carried away with my surplus shopping and now it's time to unload a few extra's. Perfect way to move up to BT30 without a huge cost.

Morning folks.

I'm just about finished with the design of a small mill. I had seen several notes on the forum that you could purchase a replacement table for the Harbor Freight Heavy Duty Mill...

I am! I'm most interested in how it mounts to the spindle itself. I can't quite picture how it was done on the original. I'd like to see where the springs mount and how the presser bar interfaced...

Marty, can you share this info? As you see in my other thread I've got a 4400M spindle and need to figure out how the original drawbar was designed/mounted.

Thanks!

Spindle taper I'm fine on, and the spindle actually came with ~10 tool holders. The taper I'm concerned with is on the opposite end of the spindle where the motor would drive a pulley. It's tapered...

So is there anything stopping me from plugging the sin/cos lines of the linear encoder in to the resolver sin/cos lines of the servo drive? I understand the processing used to determine position on...

I'm hoping to understand the fundamental difference between a sin/cos encoder and a resolver circuit.

On the surface they appear to by extremely similar. Both output two wave forms 90 degrees out...

Hi guys,

I recently acquired the spindle cartridge for a 4400M. It doesn't have the drive pulley on it, nor do I have a machine I can look at.

can anybody help me identify what the taper is...

I thought I would take the cheap route when starting my build and bought a cheap Ebay controller. Unfortunately it blew the z channel and I couldn't get it to perform as I wanted even when it did...
