@droftarts Thank you for your reply, that's very helpful I will try changing the speed then.
This is the printer they have at work and when I joined a few other people had already tried to get it working with no luck. When I went to update it I forgot to save the original config, it was on version 1. something. But it wasn't really working then anyway, so my plan was to start again so I did the config from scratch.
I have also struggled to find any information about the printer, so that explains why then.
I've managed to get some prints from it now I rewired the hot end and added a new extruder but it's just the first layer and z offset causing issues now.
I will try the things you have said, thanks again for your help.
