I have an MPU 11 kit I plan on installing on a Deckel FP4A this summer. Will this pendant from cnc 7 work with the MPU 11?

thanks Marc for info. Yes, I noticed no blister domes under some labeled blister buttons. I actually lifted the sticky and moved a few of these to correspond with button functions. Not sure if this...

sorry Marc

greetings Marc or Keith

here are pics of two Centroid? boards and membrane. they snap together. any idea what control they are compatible with?

thanks
jackson

ps-thanks Marc for the great...

I am totally pleased with my Centroid/Ajax T-39 lathe system. best value of any servo based retrofit. Marc at cncsnw is a wizard at solving Centroid problems and the go to guy.

happy centroid...

The tech team at Ajax came thru. I needed to integrate the existing handwheels on Romi cnc lathe. A simple assignment of M to handwheel axis turned function on. Even better, the handwheel feed is two...

Progress and questions. Axes 3 and 4 are now displayed on monitor. A turn of carriage handwheel results in display of incremental distance but no motion. X and Z are both displayed below true X and...

I am installing T39 lathe kit on Bridgeport Romi lathe. I would like to incorporate existing handwheels with encoders into control CNC7. TB 186says DOS based control cannot utilize Z axis mpg. Can I...

BP manual mills were available in a variety of colors. Special editions such as 50th year had distinctive colors. The cnc mills were almost always tool grey. Keep us informed on conversion progress.

Much less work and expense to purchase knee mill with built in ball screws in 2 or 3 axes. Your BP series I with 2J looks good. Resale value of a tight manual mill usually exceeds cnc knee mill with...

If your servo motors are dc brushed the Ajax retrofit should be compatible. Check with Matt at Ajax for specifics. He is really helpful. I am finishing a lathe retrofit with Ajax and will soon have...

Thanks for info. I upgraded os to ver 8.23. I will let you know how installation turns out.

Thanks CNCSNW for fast reply. I created some fuzzyness with the earlier statement. I just mounted x, z servo axis motors. They have 5000 line encoders. I connected these to cpu7 card and set PID...

I have a 5 year old Ajax kit which I am now installing. I would like to use existing encoders on Bridgeport Romi cnc lathe. Dual handwheel, factory x,z axes. These are Heidainhain 600 line encoders....

Jonne
Please tell me what type power supply you have for mill and I will suggest change in components. Gecko is recommended step driver. Also can you post pics of your machine.
thanks

I am out of helpful thoughts. George-Machintek-perhaps can resolve this puzzlement.
I notice you have Hardinge HXL. I have one also and will soon put new control on. I will let you know how...

Very nice restoration and explanation. Please explain application of Boesheild and Caswell product. What brand of coatings are you using? thanks
jackson

Mistake on earlier post. I was thinking of BP mill with series II frame, 4J head, tool changer, console with umbilical like early nc mills. Sigma or Superior steppers. Very complex machine. We...

Bart
You are working very hard to find problem. One more try. Please take transistor block from y axis and mount in z axis location. Then hook up Z wires and power up. Tell us what happens.

I notice you are in Denmark. Traub or Index machine with bar feeder would likely meet your needs. German support is nearby.

Bart
How are you checking transistors? You have to take axis transistor block out of machine to properly test. Blown or short transistor is most likely problem. Remove transistor block take...

Shift from step motor to dc servo occured with Boss 8. This was an improved operating system due to encoder feedback which reduced positioning error. It was a more complicated system and they also...

Bart
You likely have blown drive transistor in drive block. These transistors are located above and behind drive cards. Z axis transistor block is usually the top one. Each block has 4 transistors....

Bart
At bottom of swing out door where wires from step motors go into screw connector terminal block. The bottom cable wires from y motor must go into z sockets. Then power machine and move z. This...

Bart
Did you hook up y axis motor to z axis drive? This would definately tell if z motor is at fault.

Welcome jshank
I am a newbie on this forum also but have long association with step motor driven machines, mostly Bridgeport Boss.

The NTE386 transistor is direct fit for the BP Boss machines. If you are in Arizona you are lucky. Boss machines do not like cold shops and will blow transistors like crazy when cold. Most of...
