I just dug out my old CTC Dual 3d printer and decided to update the firmware to Sailfish. After updating to Sailfish 7.6, the left extruder was trying to print way over to the right after a bit of crashing into the left hand end of the galley. I found the manual for Sailfish online and realised the Head offset for dual extrusion was off. There was no option to change the head offset in 7.6 so I upgraded the firmware again to 7.7 which has the option to change it. I was shocked to find that the head offset was set at 330mm when it should have been 33mm (34 for mine actual) according to the Sailfish manual.
Was this 10x error down to something I did when upgrading to Sailfish or was it already in the already in the firmware I downloaded ?
If it was already in the firmware then I think it should be corrected so as not to damage printers.

Having the same issue, will try to upgrade firmware and set offset, are you still using replicatorg?

For slicing I’m using Makerware 2.4.1.24 mainly, but have used ReplicatorG 40r33 a couple of times.
