Hi Piete,
Hmm, doesn't look very nice...definitely looks more like a pancake(.io) than a print :-) Have you already been able to solve this problem? It is important that you a) set the correct step-size in the firmware (eg. 106.76) corresponding to b) the correct microstepping (eg. 1/16), set by the jumpers on the RAMPS board. Unfortunately, the Sumpod wiki is currently down and I am not sitting in front of my printer to check what microstepping value is set by default. However, to check, move your z axis 20mm with your software and measure. If you get 10mm, your microstepping setting doesn't correspond to your configured step-size. You either have to double the step-size in the firmware or half the microstepps (1/16 -> 1/8) on the RAMPS.
As you mentioned on the official forum, it could also be too much current on the driver. However, you could see the movement being interrupted when moving the axis over a longer distance by the software.
Good luck!
Cheers, Andy

Hey Sypher
Have you been able to answer your questions in the meantime? Otherwise go ahead!

Hi Piete
A late but very warm welcome to the forum. At the moment, there is not much going on here, but I hope this will change over time. For my part, I just took my 'pod out of the shelve again two weeks ago, after the first frustration of last spring had passed.
Congrats for your blog. It is very detailed and I am sure it will be a huge help for others who purchased the aluminium 'pod. As I am a original owner, I cannot help a lot concerning specific parts of the aluminium version. However, as several parts are quite similar (e.g. hot end), the whole system doesn't seem to be too different. Feel free to ask, whenever you get stuck, need an opinion or a field report.
Regards, Highcooley

Yessss, this is my first print after the upgrade to the fan less hot end (and my first longer / bigger print ever). It's the first part of Airtripper's fabulous Pocket Filament Reel Rollers, which look amazing and is amazingly simple to print and build. Done with Marlin on Repetier Host, sliced with slic3r at 35/45 mm/s at 195°C. Any suggestions, how to get rid of all these pimples sticking out of the print during the print or to improve the quality in general? Attachments:

Hey fellow Sumpod owners
Does anybody have experience with the Hot End upgrade (without heat sink) for the original Sumpod, he or she would like to share? I did the mechanical part yesterday and plan to fire it up this evening for the first time. Having had a hard time with the old Hot End (see my endless posts on Sumpod.com), I would be interested in tips and tricks like distance of the heater block to the nozzle tip, how many layers of capton tape you applied, and so on.
Then I also upgraded to the dual extruder directly. As suspected and mentioned to Richard beforehand, the alignment of the nozzles in Z is a freakin pain in the ... How did you solve that? Might it be a good idea to sand both tips to the same Z height?
Thank you for your reply and lets breathe some life into this forum!
Cheers, Andy
