z is set to be on always. the controller it's not overheating and only one of the 2 z steppers it's stopping, so, I think I will disassemble and reassemble everything. Must be something mechanic.by dagusi - General
ok, after first test I can say: PLA doesn't stick to he glass, it's like PTFE so that's GOOD!!!!!!!!! sadly, it does leak in the gap between the glass and the nozzle (as expected) but I don't know how to sole it yet Screws transfer a lot of heat, I need to do something there, really really a lot of heat IF we can isolate the top aluminum part, from heat, we could have a hot end without a fan laby dagusi - General
QuoteA2 @dagusi I like your prototype Heater vs. Mass: The picture makes the aluminum block look large. The aluminum mass might be too big if the heater is small or located too far from the nozzle with a larger mass. Coat the heater with thermal compound to help conduct the heat. I would be inclined to use a cartridge heater for this application, and locate it as close as you can to the nozzlby dagusi - General
Ok, this has been in halt for a while but finally I have my proof of concept assembled, noy I need to figure out a good way to put the thermistor here, generate the table for that thermistor, recompile marlyn and give it a go, just at a side not mounted on the printer yet, just feeding filament by hand. wish me luck! ;P keep you posted.by dagusi - General
current it's ok, I will try with the speed change. on KISslicer I have it on 6mm/s and works ok, on slicer I don't see an option for Z speed, I will check the settings on marlin and repetier.by dagusi - General
Sorry but I don't know if there it's a better place to ask this. I have a mendel90 variation printer with ramps 1.4 on an arduino UNO and 4 pololous a4988, I'm running marlin on the arduino and repetier host on the PC (I dont have the SD reader, it's on the way from china) I usually use KISslicer for my gcode but some models and single wall spiral vases are sliced on slic3r, works better.

Interesting, I was thinking in make a Thermal Brake with glass and you already have 1/2 way in. I think if the glass it's over 120 °C pla will not stick (I've made some proof of concept with sheets of glass) it's not definitive, but I hope to try soon with a proper tube. On the gap clearance thing, I think if you have reached X temperature the expansion will stabilize, therefore you can just usby dagusi - General
