Microswiss all metal Hotend
Just a quick note to this old post about changing to the Microswiss all metal hotend. I'm a machinist and noticed like many, the new nozzles fit rather sloppy. So I emailed MS about it and they replied they machine them smaller due to the variances from one machine to another's cooling bar tolerances. So, using an inside mic to measure the bore of my cooling bar and an outside mic to measure the MS nozzles I ended up with .007" difference. Took a Pepsi can and cut it apart, sanded off all the paint and sealer on both sides, ended up with a .003" shim stock. Cut it to just fit the bore of the cooling bar, smeared a very thin layer of the silver compound they sent on both sides of the shim, some in the bore and on the nozzle. Naturally most of it smeared off. It went together with near zero clearance. Works like a charm and printed much better than the stock nozzles. I didn't have to mess with fans, didn't have to mess with the temps at all and overall I feel it was a worthy upgrade. So for anyone having issues with the MS hotends this resolves the bad fit from nozzle to cooling bar, give it a try.
Please explain to me how to...
