Not Printing in Centre of Build Plate

Hey there

i am having real difficulty in getting the printer to print in the centre of the build plate.
Please help,
i have tried the toolhead offset but it does not seem to work.

I have a Velleman K8400 Vertex with a E3d V6

Well you definitely don't want to be messing with the toolhead offsets. That's probably not the right setting to adjust.

First of all, are you using the stock K8400 profile that is already provided by Simplify3D from the configuration assistant? It might also help if you post a picture of your printer's bed, showing where the nozzle homes and where it moves to when printing.

Thank You for the reply

yes i started with the stock settings, but as i am using Colorfabb XT i have been playing with them to get it right.

If you look at the printer it homes to the right and away from you. As i mentioned i have a E3d V6 and due to this i have placed the hotted in the second extruder position. When i print in the centre it comes out too far to the left 12mm (x axis) and to close to the front 30mm (y axis).

Re: Not Printing in Centre of Build Plate

Ok, well the first thing I would do is the following 2 tests.

1) Go to the S3D Machine Control Panel, click on the Jog Controls tab, and then hit "Home All". Note where the printer moves to. Next, go to the Communication tab and enter "G1 X0 Y0 F3000". Where does the printer move now? Does it stay in the same place or does it move some to a different place on the bed?

2) After you have done the steps above, then go to the Jog Controls tab and use the X and Y jog buttons to jog the toolhead to the maximum XY dimensions of the bed. Keep track of how far you move the print head. You can also use the position readouts in the top right of the MCP if you want. Once the nozzle gets to the far corner of the bed, record how far it moved in the X and Y axes. You could also measure this with a ruler or something, but I find that actually jogging it in the software is more reliable, since you get a better feeling for the clearances of the nozzle as it moves.

If you do those 2 things, it should be easy to figure out what settings to change :D
