... Sorry but all y know is that we change all de board in 1998 and it was very expensive. like $6000. Your best goal is to Check in Ebay Or maybe as to this...

Hello Graham, In your searches, did you find a specification sheet for the S-203DS1? If so, once the relay's ratings are known it should be easy to find a...
Hi does anyone have the setup software disk for the Roland SYA-350 buffer unit? I just need the files off it to create my own [ I think!] Thanks in advance, ...
My old (purchased in 1988) and trusty CAMM3 has given me it's first problem. The machine was working fine and in the middle of a project the spindle motor...
Sounds like one, or all, of the power supplies went out. Almost all of the electrical problems I have had with the CAMM3 have been mechanical in nature - by...
Hi All, Still having problems with my Camm 3 the XYZ all works fine and the motor runs OK if connected to the mains, just had the motor controller board back...
Graham, Try cleaning the optical encoder under the front drive pulley. If it gets dirty from dust and belt debris, it can’t read the timing marks and the...
From the control board, can you turn on and off the "sensor" that is used for Z axis setting? You should see the LED turn on and off. That would eliminate...
Hi Andrew, Thanks for reply, just checked z zero device and that works OK, Im not sure how to check the signal from main board, I can see the 4 colour wires...
The motor timing device Is separate from the motor control. The motor control signal branches out to the timer, but it is not in the control path. You could...
Graham, Just took the back off my Camm3. The 4 wires going to the motor controller board come off the main board on J304, which is easy to get at. With my...
hi andrew, thanks for that detailed instruction, just to clarify to check the voltages here do i keep the black pin of my multimeter on no. 3 pin [gnd] and...
Graham, If you remove the top plastic cowling over the spindle you can easily see the motor speed sensor board. With the Camm3 powered up and the motor off: ...
Hi Andrew, I checked the voltages and action on the 4 pins and they do exactly as you described so the main board is OK [phew!] which leads me back to the...
Just checked the sensor board contacts and they are OK, However I re-checked the pins from the contoller board and pin 4 is at 1.8V and not 12.5V? Graham....
Well that would be the problem. Â Double check your measurements just to be sure. This means the main 12V supply has quit. I'll look at the schematic later...
The 12V supply is used mainly for the motor speed control and feedback. It is not surprising that most of the Camm3 would continue to work without this...
Hi Andrew, OK Ive checked the board nothing looks burnt although there is some goo? [glue?] at the base of L1,C3,C5 Ive noticed this on a previous Camm3 and...
Graham, The problem is somewhere in the power supply circuit on the bottom of the Main Board. Â It is likely the transistor TR1, or diode D1, or the IR3M02...
Hi Andrew, Thanks very much for your help, It will give me a head start when I speak to my electronics repairer next week, I will let you know how I get on,...
Hi Andrew its me again! I have replaced Transistor TR1 and capacitor C4 and checked the voltages,TR1 is at 35-40V and the 12 Volt supply is a bit more than...
Sounds like you may have a bad connection somewhere. In a message dated 4/10/2013 8:24:02 A.M. Pacific Daylight Time, cadcamcreations@... writes: Hi Andrew...
Hi, Yes maybe but where? It looks fine and Ive checked all over! Regards Graham. ... From: clwphstd <clwphstd@...> To: CAMM-3 <CAMM-3@yahoogroups.com> ...
Hi Graham. Well, everywhere. There are a couple of things you can do... The "cave-man approach": Start "GENTALY" tugging on all the wires and see if...
