@Mike_Smith , it might actually need double the distance between the hot ends? I’m not totally sure.
Will you need to use something besides water? Mineral oil?
@Brett_Giesler de-ionized, filtered water is not conductive.
No, I meant b/c the extruder is 230C? how big a pump will you need? Will it boil in the lines?
@Mike_Smith well, either will have its challenges, flat is best for structural integrity but you need to enable supports to stop the edges from sagging. If you’ve not printed them when you read this, hold on for a few more hours. I’ve tweaked them a little to optimise the alignment of the bobbins.
@Brett_Giesler the heater blocks get that hot, it doesn’t get near that hot at the water block. The water block itself is likely to be completely touchable.
@Tim_Rastall Nope I haven’t printed anything yet. I was planning to start tomorrow. I’ve already downloaded the files so I’ll just delete those that I have and re-download after you update them. Thanks for the heads up. Let me know when they are updated…Thanks. Also @ThantiK had mentioned to me that you have a lead on where to order the T-Slot from, any help there would be appreciated.

@Paolo_Amboni the only hardware I know of is printrboard with its expansion module. I’m going to make a sheild for a 7th driver on my RUMBA it already has enough thermistor ports and 12v PWMs.
Marlin needs some code changes but people are working on it.
@Mike_Smith new bearing mounts up on youmagine. You need to print 4of the upper ones and 2 each of A and B lower ones
@Tim_Rastall how tight should the bearing fit in the bearing mount. I printed one of the upper mounts and after cleaning out the support the bearing fits a little loose. Not to the point that it can move back and forth but it just slips right in and I can spin it around and it slides right out without any prying.
@Mike_Smith when I printed them the bearings slid in with a bit of pressure. Dimensional accuracy of your bot may play a part. As long as there is no slop, use a bit of glue, if there is slop, scale by 0.95 and reprint.
@Tim_Rastall Thanks…I thought it might be a difference between machines.
