Great forum, already got me started with printing.
I've tried the following.
1. Netfab (pad version)
2. ReplicatorG Ultimaker 35
3. Cura
4. Marlin v3, (and v2 and v1) and the default ship 5D
So I've got the 20mm cube, it sticks fine to the surface, it starts well, but after 4mm it goes wrong, the cube becomes offset by about 5mm a big jump, then it all get's worse as it tried to print the cube and jumps again.
I was also getting a gradual offset, tiny amounts layer by layer. The offste seems to be in the Y axis.
Is this a hardware of software problem?
I did add the Marlin v3 using the RepG software, the Cura won't connect now to the printer, where it was when I installed the Marlin v3 using the Cura wizard.
Well I've a lot to learn, but that's all part of this world!
