smalljoshua Posted April 15, 2009 Share Posted April 15, 2009 Hello World :P As the title says really. I have the PCB out of one of my Roboscan Pro 218s in front of me. It has a fault making the Tilt Stepper very jittery. I have swooped the board for a known working one to rule out the Stepper and Loom leaving me with just the PCB. I am looking for somewhere where I can send the board for them to either fix or replace the board. Alternatively, I am looking for someone with a Martin Roboscan Pro 218 MK2 PCB that they are willing to sell me. Many Thanks. Josh Link to comment Share on other sites More sharing options...
Happy Jack Posted April 16, 2009 Share Posted April 16, 2009 Get in touch with Jamie Shurlock. I'd be very surprised if he couldn't help. He is a member here, maybe the mods could point you in the right direction. His home page is here, http://s262510961.e-shop.info/shop/page/1?shop_param= Good luck!

Kinell Posted April 16, 2009 Share Posted April 16, 2009 I might have one in a shed somewhere, we robbed most of the other internals to build some working ones so might still have a case with PCB in it, I'll try to take a look tomorrow. Link to comment Share on other sites More sharing options...
smalljoshua Posted April 16, 2009 Author Share Posted April 16, 2009 Thank you for the replies. I will follow both of these leads up. Josh Link to comment Share on other sites More sharing options...
Modge Posted April 16, 2009 Share Posted April 16, 2009 Dave Moore (PM me for his email address: he appears to be between websites at the minute...) has a load of 218 mk2's, some of which IIRC are in spares \ repairs condition. I'm sure he could be convinced to part with ether a unit or possibly just the pcb. Link to comment Share on other sites More sharing options...

JoshSounds like the ULN 2803 16 pin dil chip, I am not sure but this usually is in a socket next to the stepper plug socket, or it is a desolder job, but still fairly easy with an iron, you can check for this by swopping pan and tilt plugs, if the problem moves to the new motor it is definately the ULN chip.

smalljoshua Posted April 16, 2009 Author Share Posted April 16, 2009 Those chips are next to the other Stepper connectors. The chips nearest the Pan and Tilt connectors are marked PBL 3771. Josh Link to comment Share on other sites More sharing options...
