The park buttons are similar, I had to disable the macros assigned to those to keep from accidentally crashing things.

Craig

Could probably make that work it there was a way to trigger the macro when the value changed, however the PWM value would have already been calculated by then. However, I think it may be possible to...

I would like to have the ability to look at the S-word in the G-Code or being entered via the MDI so I can change the maximun and minimum Spindle RPM values for the PWM. I have a step pulley system...

Woohoo!!! That works for me. In the documentation I have, 900 is called the Profile_name so I didn't think to try and use it. Was thinking more about the scrolling window just above it. Do you...

vmax549,
That is exactly what I would like to do, the MessageBox.Show seems very buggy, I could not find any documentation on how to write to the message bar. Can give me the particulars on how...

I am making progress transitioning from Mach3 to the UCCNC application using the UC300-5LPT. Built a couple of boards to galvanically (opti-isolate) the UC300-5LPT board from my switch pendant,...

Gerry,
I looked in the user manual and couldn't find a definitive answer to weather I and J were relative or absolute. The only thing I found was: "In both formats the axis coordinates mean the...

I have been testing the UC300-5LPT with a couple of BOB boards I built for my machine. Here is my list of needs:

1) Support for M00 (I think that will be in the next release)

2 Spindle step...

Been using Mach3 for the last couple of years on my Bridgeport conversion. The PC needed an update from Windows 2000 to something modern but I couldn't get the second PP port card to work under W7 so...

The UCCNC controller, Mach3 plugin or the driver identifies the the UC100 or UC300 hardware in conjunction with the license file enables full operation. The software will run in demo mode on any...

So it looks like you have spacer balls. I would just measure a few of each size to try and get a sense to the nominal size of the large ones and the small ones. Then go get some new ones from...

Chuck,
Generally you fill the tracks and return tubes full but not to the point where its packed tight. A ball space or so less is not an issue. Make sure you measure the balls, some of them may...

Just have to cast in a place to feed shop air to the interface. Lots of square inches at 150 psi should do the release trick. If that is still not enough a hand hydraulic pump would.

Craig

You did measure the ball diameter didn't you? Some times they build the ball screws with alternating very slightly smaller diameter (few tenths) balls to take off some of the drag. It acts like...

Funny, I have been thinking about doing some sort of probe off and on for several years. I think Ken has a good list of requirements. I would add a couple more, 8- low false triggering rate 9- ...

Was doing the final painting on my BP mill refurb project with some white urethane paint. Looked nice with no runs but before the paint had a chance to set up a swarm of bees flew over raining yellow...

The knee is a 5 TPI lead screw
Steppers were easer and lower cost vs servos. Resolution is about the same. On my x and Y the pulse scaling is 20,000 pulses per inch when using the Gecko 203V that...

Hi,
I converted a 1966 step pulley J head BP 9x 42 to CNC. Here is a list of my drive components. After updating with ball screws I can do 100"/minute but have kept it down to 75"/min max for...

Basically it was a drop in. Because it was an ebay special I did have an issue wiht the Y axis nut mounting on the yoke. You can buy a kit from Rockford that has it all ready to go. Bridgeport...

I also had some significant backlash and was told cutting the acme nut into two sections could help. Even built a tightening ring system to put even pressure on the nut. The ring tightener worked...

Hi,
I had a similar problem, had to do with the Constant Velocit setting in Mach. The X or y was starting up befoe the Z finished up decelerating to keep the tool moving at a constant velocity in...

Yesterday I completed the last items on the mobile base and slid it under the Bridgeport for a test drive. It fit perfect, the mounting holes were all aligned. As expected the rear wheel fully...

There was quiete a difference between the old acme nut and the new ball screw. I suspect it was mainly just nut friction that limited the speed. Its hard to know -- I would just set the acceleration...

I converted my 66 J head to a Ball screw for the Z. Installed a 1.5" dia 5 TPI ground screw I found on ebay. The knee lead screw on my CNC conversion is driven directly through a 3:1 timing belt...

Uneven filling of the cylinders will not really be a problem.

All the cylinders have the same throw and volume in addition the throw is mechanically limited by the wheel assembly to 2.25". ...

You are correct two on the the sides of the dolly up just behind the leveler pads and one center castering wheel in the rear. The weight distribution should be on the order of 800-900# on each side...

Over the past few weeks I have been working on the main base weldment. I finished up the the final grinding this morning then loaded her in the pickup for a trip to BR&F Spray to get media blasted...

My Teco 7300CV (1hp) dynamic braking doesn't work anymore. Initially the feature worked OK and I could set the rate parameters now the ramp down is the same no matter what value I use. I suspect a...

The windings on the stepper motor have both resistance (measured in ohms) and inductance (measured in micor henrys). When the motor is buit they have specific values based on the design of the...

Today I did a little TIG welding and sealed off the end of the hydraulic cylinder for the rear wheel assembly. Also welded a flange to the other end. I need to do a lot more practice on the TIG! ...
