Multicam MG 103 1999 - Parts

Just picked up a Multicam MG 103. It looks like it has cut a lot of wood in its day. I have some specific parts Id like to get right away.

• Linear rail cover for the X axis. One side must have come off. (should I worry about this?) Gantry has to be removed for installation?
• Bearing Cars - Not sure I need them yet. 1666-294-11 is the part number on them ( I think), are these Rexroth? (AA08K is this the production date?) The rail width is 20mm.

If I gave Multicam the serial number do you think they would tell me the service history?

Nice find!

If you're slick you might be able to slip the cover under the bearing cars. Multicam can be helpful depending on who you talk to. I recall getting ahold of a lovely and expert guy named Eric last year. If you're ever interested to retrofit this with a modern controller and need help please get in touch.

A year later and I have movement. I've completely redone the main control panel, added a larger control panel on the Y axis, and have a new switch control interface.

Right now, I could use help with is setting the steps per inch on all the axis. My last machine was easier to calculate this since the steppers were directly coupled. I know these steps per unit questions get posted all the time. So I did a fair bit of searching before posting this, I've found great answers.

With this build I am using the ClearPath servos.
