I have been using my Ormerod 2 fairly regularly for the last few years. Yesterday I needed a print that used most of the bed area. I am finding that the first layer does not seem to extrude as much PLA when the X value is greater than about 120. Instead of consecutive lines merging together, there is a gap between them. I had not changed any settings when this occurred and have done similar sized prints in the past.
I have manually re-levelled the bed and reset the Z home height. Also increased temperature of hot end and bed. I have even moved the extruder to the central position on the X-arm to reduce strain on the PTFE tube - nothing has improved the situation. I have carried out the standard maintenance (nozzle clean, lube, belt tension etc)
Does anyone have any suggestions please? I am getting quite desperate to get a decent print again. Smallish prints are fine.
Thanks
Bob

It sounds like you need to use mesh bed compensation.

Thanks DC42.
I don't know why it took me so long to find the problem, but it was actually the Z sensor moving slightly when the printer was carrying out the bed compensation readings. A dab of superglue fixed it!
That said, I think it is time I carried out some updates. Is your Z probe board still available, and can you point me at a link for your latest firmware (and instructions) please? I am still using the original RepRapPro firmware.

I'm glad you found the problem. I no longer sell the Ormerod-specific hot end board, but the mini IR sensor is available here [www.duet3d.com] and from E3D and other Duet3D distributors.
