In the position I show in the photo the timing was within range of the Epsons normal paper sensor and printed without any problems. If you have made new bushings you should be able to get a normal PCB thru without difficulty. My bushings lowered by .100" plus the normal printer gap gave me plenty of room for .625" PCB and the carrier.

Hello Willian, thank you for the answer.
As I understand it, you have managed to place the sensor on a position that it will be activated by the pcb at the same time that it would be activated by the paper and feed mechanism on normal operation, is this it? It sounds easyer then logging and simulation the sensor behaivor, I will try this aproach.
I will try first to print on very thin PCBs (0.005"), wich I believe will need only a straith feed path - think it will not be necessary to move the print head up. Need to solve this sensor issue first tought.
Then, I plain to cut the body of the printer to raise all the head structure. I plain to build in wood a "base" to fit the PCBs that I plain to draw - dunno if I made myself clear here. I plain to make this base to fit exactly the feed mechanism, to make the printer more accurate. I plain to make the PCBS be at the same position on the base allways, to try to make double sided PCBs.
As I don't have much knowleadge on mechanics and a limited toolset, I can only hope to have success. Any input or tip is appreciated, apart from all the information on this group message history.
