HELP Needed!!! Tdozer R1900 build

Dirty Star said:

Right i turned my printer on for the first time and the printer head shot across to the left and there was a loud grinding noise! which was coming from the left hand side of the frame. Its coming from the belt that drives the printer head, like if theres gears jumpinf or grinding. can anyone offer any help??

many thanks

sounds like a connection issue with wiring/ ie wrong cable to socket/ plugged in backwards etc..

this is the most frequent reason for the run away carriage.. double check all your wiring/connections..

thanks for the quick reply. I'm gonna take all the plugs out and put them back in. I knew it wouldn't work first time, now comes the hardest bit. Also i just wanna say a big thanks to you and spiderx1 for the cluebook. I'm just starting my own clothing label here in the uk. Cos of this build i've got future/career ahead of me. Big thanks to everyone here

I switched the wires around for the CR motor and it moved better but then went into the right side of the frame where as before it went into the left. The ribbons seem to be in the correct plugs, they face either front or back and match the plug pins if that makes sense....am i looking at the correct wires?? could it be the pump motor wiring?? Or should i concentrate on the ribbons?? Theres a ground wire which is still on the frame. I've checked the wires over with a multimeter and im getting good readings so the soldering is fine.

Can anyone offer tips as to where i should be looking cos im clueless now

thanks. kully

can the CR sensor be at fault? I checked in the service manual in the trouble shooting section and it said if the carriage hits the sides of the frame, the CR scale or CR sensor could be at fault because they may be damaged or dirty from dust. There could be dust or dirt in there from the MDF i was using

Just clean encoder strip and sensor and see what happens.
I`ve the same problem. Encoder strip in my printer was dirty.

well after putting on anew encoder strip , it still did the same thing I've had a look at cleaning the CR encoder and that is a lot of work that i don't know if i can do, basically involves taking the carriage apart......think my next option is to buy another printer. I am so disappointed
