Retrofiting Scm record 220

So on a different note this has a stepper drive and motor for the umbrella tool changer and the input is serial, it is an ever electronica drive scm01-09. So wondering if anybody as dealt with this. The manual talks about writing and compiling programs for it in dos.maybe there is some long lost hal file somewhere.?

I don't know. Our SCM machine's stepper drive for the tool changer is from RTA Motion Systems, and is controlled by 3 signals from the control, a direction signal, a start signal, and a stop signal (step pulses are generated internally.) The stop signal is a combination of a couple outputs from the control, some proximity sensors and (I think) the e-stop button. But there is no serial connection used.

I have this idea about hacking into the drive between the logic side and the isolation to main transistor's and run off a mesa card and hal. Has anybody tried something like that. I have a fanuc robot project that would benefit from this also.

Hi....I am new to this forum. I have a faulty NUM controller card for the SCM Record 220.  I can get a service exchange card from NUM for about $1500. Seems a lot. Is there any other option? We believe the problem is the card because when we replaced the card with one from another machine, it worked. The part number is 0204204478

While we do have an older SCM CNC machine here (and it is still running it's original control.) I am far from familiar enough with them to be able to tell you what your bad part even is just from the part number. What does the part do, what does it look like?

Also even though this thread was about helping someone retrofitting a Record 220 like yours, doesn't necessarily mean that it was the same or used the same control hardware. SCM made these machines over a long time period and offered many different options and fitted different controls over the years.

Hi there,

I recently bought very cheap record 220, but in non working condition since battery is dead in num 1040 controller.
Already have replacement BOB but now thinking why not try to fix original unit since everything is ready for it and machine also have 4th axis(that dont accept step/dir) and drilling unit.
Should I try to repair Num or take a time to connect everything with new BoB that would probably not been able to drive all in/outs and 4.axis?

 Its uc300eth-max, about 20output and 45input.
Machine still have much more but its certanly enough if make connections more simply.

Thing is am not sure should I mess up factory instalations or maybe its better to get controller fixed and just threw it in and go, would benefit from 4.axis which motor is driven analog (tool turret maybe too) and I guess its professional nc. and is probably better quality and reliability that of diy approach.

On the other hand with new bob would have more possibility, like 4.axis on table rotation and add diode laser or plasma torch.

Have already tried those Yaskawa servos and are working with step/dir signal, just had some problem with endless motor vibration on X axis with smallest move of shaft.
Have swap it with Y drive and they work fine, its only happening with X drive on X servo.

Am not worried about tools turret since if cant work with step/dir its a small motor and probably have some stepper laying around that can replace it.

Here is pic of the drive for the 4.axis (tilting spindle head on sides).
Midi Maestro 140x8/16
 
 

Would like to add that I dont see too much use of tilting spindle axis anyway, maybe am wrong?
But have idea.. What if could just tilt it with one potentiometer to desired angle, in that case could still use it to drill holes at angle with drilling unit and cut board at angle.
Also could cut fully at edge of the table since my Y axis now has longer travel than width of the table.
Machine came with 3.2m x 1.55m travel but there was some distancer on Y that has limit travel to about 1.25m which is width of the table.
Now I took off that distancer and its free to go, just need to move that limit switch but it already have a place designed at 1.25m and other at 1.55m.
So think I will use both limits with a switch to chose between them so sometimes can have better travel.
