Is the hotend hitting ridges left in the first layer of the filament or just kind of dragging along the top of the extruded filament?
I had the ridge issue myself before I gave up and took a break. I think it is caused by the nozzle being to close to the bed, so the filament overflows and forms a valley whose edges are higher than the layer height. Occasionally, if I could just manage to print the second layer, the issue resolved itself and finished fine.
Now that I am working on my printer again however, I have had the nozzle dragging along the top of the extruded filament though on one or two tests. In that case, I believe the issue was caused by the nozzle not lifting during retracts. As there is no dedicated motor for the Z height like there is on cartisian printers, I believe it is always beneficial to enable Z lift in your slicing software for delta style printers. Hopefully someone else can confirm that however.

Can it be that there is some kind of buffer issue if you print too fast? It seems that my printer can follow quite well, but still it blocks every once in a while (= a few times per layer) for about 100-400msec or so. It seems to wait for a commands from the PC.
Maybe something to do with the baudrate (set to 250000)?

Aah :-) Now I start to understand the difference between the RAMPS and Smoothie, Duet etc :-)
Do you have any preference as to which to try out next? I have only knowledge of the RAMPS board, but didn't try out the others yet. They also seem to be significantly more expensive than the RAMPS board...
I do have an option to add an SD card. I didn't yet try to do it this way, as I first focused on getting the printer to work :-) Will try that this evening! If this increases the max speed, I will make it that all G code is uploaded to the SD card first and that then the print starts. This way, I hope to (partly) circumvent the limitations of the RAMPS/Arduino board :-)

The Duet also has FTP Access to the SD CARD (Which is where the configs are held for both DUET and Smoothie for that matter).

Hey guys!
Thanks for all the response! It seems like these boards are indeed quite good, and I already noticed the excellent LCD screen of dc42. Sadly, living in Belgium, it is hard to come by 3D printer stuff, and as such I can only buy this online in the US or other countries. I have had some bad experiences with customs who put a hell of a lot of import taxes on products I bought online, so I will have to look into that :-)
I will this evening try out the SD card and see if that already helps a bit. If it does, I will try to upload the G code wirelessly, so I can at least continue until I find a suitable replacement for my board.

Ah I thought import taxes were always if it came abroad :-) Must then only be from outside the EU...

I so have ordered the Duet Printer Board, but sadly, I will only be able to work on it in 2 weeks (will be delivered at parents home)... Hope it won't require a huge learning curve again as it did with the calibration of the RAMPS :-)

Does your printer have a Z probe, and if so, what sort? If it does, and the type of probe is already supported by the firmware or I can easily add it for you, then you need only get the endstop switches approximately even and set the homed height slightly higher than actual. The auto-calibration facility in the firmware will then sort out the endstop corrections, delta radius, and homed height.
