I've been using the UC-300 and a C32 BOB for a couple of months now. I really couldn't be happier with it. I haven't run into any big issues at all.  There were a few minor bumps that Balazs and Arturo fixed right up.

I have another machine with a first generation smooth stepper and the differences between where he smooth stepper was at its release and where the UC-300 is are huge. Not trying to bash the Smooth stepper but I was less than happy with it ( and still am) when it came out.    I'm using the UC300-LPT and cables to interface it to the C32. I also have a Kflop and although it' an amazing piece of hardware the interface between Mach and the Kflop was too technical for me.

If I was to do another machine I wouldn't hesitate to use this combo again.


Hi Scott
I had 2 issues with my setup.
The first one was bad solder joints on the 4 pins that connect it to the drive.

The other was tougher and I never really solved it. Although I really didn't try too hard.  I couldn't get it to recognize the drive through the XP machine I have on the computer. I ended up rolling over my shop XP machine that I use for testing and such and used it to tune the drives.

I know this doesn't help much but it's all I got :)

On the plus side the drives and the UC300 motion card are awesome.

Hi Hood

You may be right but I'm almost positive that it wasn't a problem with the old XML. I was using the old XML when I first got it fired up and running with the new motion controller. I went with a virgin XML because I wanted to start with a clean slate. I'll load the old XML tomorrow morning and see what gives.

Hi Hood
I'm running .056.
My old XML has no issues with this version. This isn't the first time I've had a new XML not perform the same as an old one.


General Mach Discussion / Rotational soft limit issue
« on: August 08, 2013, 07:49:31 AM »
I've redone the config for my mill.
I started with a clean XML. I can't seem to get the rotational soft limits to be ignored. I had no problems with this in the old XML.
I have "Rot 360 Rollover and Ang Short Rot on G0" checked. I have "Rotational Soft Limits" unchecked. I can increase the the distance in "Homing Limits" but that's not really the solution I'm looking for.
I examined the Rotsoft parameter and it was set to 0.

Any thoughts on this or is it yet another "wait for Mach4 issue".

On rolled ball screws is the exterior concentric with the lands? I was always under the assumption that you needed to indicate the screw where the ball rides.

I tried machining a few ball screws and they were a problem. It's really hard to get the screw true in the chuck. I ended up replacing all 3 72" screws on my router with pre machined screws.

I'm not trying to discourage anyone that has the screws already but if you're trying to save money by machining your own…..don't. Spend the bucks and buy them machined.


I have a customer that wants me to start engraving tags for him. Was that stuff easy to work with?


+1 for 145Deg

Here's a really good rub recipe I got from the webber app. I grind everything up in an old blade type coffee grinder.

3 tablespoons kosher salt
3 tablespoons whole black peppercorns
2 tablespoons granulated sugar
1-½ tablespoons whole mustard seed
1-½ tablespoons sweet paprika
2 teaspoons dried oregano
1-½ teaspoons whole cumin seed
1-½ teaspoons whole fennel seed
1-½ teaspoons celery seed
1-½ teaspoons crushed red pepper flakes
1 teaspoon dried thyme

Nice plate by the way!
