When I grab the underside of the turret motor of the Turn 55, I can pull it up quite a bit so the is so play in it. To improve the accuracy it want it to be solid and I think I have to set the hex

Hi, My machine works perfectly as far as the steppers are concerned so I am loathe to change anything. I like restoring machines to their original specification so I'm afraid the Chinese Upgrade is

Hi Ron, As far as I am aware the floppy only stores the G Code which is currently in the machine memory. I have never had the disk working so I couldn't say if it stores anything else. Hopefully I

I have work whit the 6800 and 6502 and I guess that I still have part in my place. But it have no sens to put that lot of time in a pcb board like that. You have to write new code in machine language

Hi Robin, Its good to hear that someone else has a FDD on their C5. Mine shows no sign of life whatever not even a flashing light. I have read that some of the machines will only work with certain

I would also be interested in any data you get on the floppy system. My VMC100 with T2 also had a floppy installed that has never worked. I switched with a tape drive and it's fine but the floppy

Hi Simon, Thanks for your reply. I am currently in the process of drawing out what I have found on the machine. I did do some work with 6800 series chips in the 1980's but have forgotten most of what

Hi Keith, I'm in exactly the same situation as you are, except mine is a later model (?): serial number A6 AH 9027 and was made with the FDD from new I think. It has hardly been used and is

Buddy, The way to go at this is to study the data sheets for the CPU & the diskette controller. As a long time UP system designer, I can say that with LSI parts like that you just collect the

Hello All, Does anyone have a copy of the main CPU schematic for the Compact 5 CPU? I have been restoring my late (1987) Compact 5 CNC for the past few months and it is now cleaned up and almost fully

Steve, Have you looked at the Buildbotics controller? IT saved me a lot of time and money on my PC50. Doug the owner is a great help. Sincerely, Joe Schlawin President and Owner JRS2TOOLS and

You will also have to replace the spindle motor. Lesson makes a 5hp metric frame motor that would fit the motor pulley. VFD will be spendy. 3HP motor may do you well. Depends on the parts you plan on

I bought a VMC100 that is refitted with USB CNC, but the spindle has some problems. Now I want to replace by a 3kw ELTE spindle that I have lying around, but this one is bigger then 80mm round. I want

Acorn, Ether1616, 400w DMM AC servos, use the index pulse for homing or buy closed loop hybrid NEMA 34 Hybrid stepper, or Clearpath SDSK motors and reuse the proximity sensors that Emco used to home

I didn't think I would win this auction, but I did. Now the issue is whether to run it as-is or update the control. I did watch some YT video's with Marty Escarcega so I am leaning toward new servo's
