| BillTodd:
This is going well... (probably should not have said that) I had to rewire the mains connector because the wires were an inch too short. Interestingly the 'as used in the school from where I bought it' , wiring was arse-about-face ! :zap: I'd had a couple of minor buzzes from the thing while it was switched off and was a little puzzled as to why. The live and neutral was swapped on the IEC connector so that the switch was in the neutral side ! |
| BillTodd:
It's going .. Well, I really should not have said that. However, once dialed in the first layer was quite good, and until the extruder seized and the part cooler fan refused to start without a flick , it was looking like a printer again. |
| BillTodd:
After a fight with Marlin's config and a string of adhesion issues , I have almost managed to print something :D A typical Benchy The bottom third looks ok-ish Then , after adjusting the cooling , the hot-end faulted with a 'runaway' error (the original cooling fan broke so i was running a bodged up thing ) It resumed the print but reset the 100% flow until I noticed. Unfortunately, I tweaked the speed down to 95% instead of the flow and scratched my head until I noticed . By then it was a complete mess so I wound the speed up to 200% ... and spat it off the bed . |
| BillTodd:
I have a benchy, it's crap - no cooling - but it was started from cold without intervention and it completed . |
| BillTodd:
With cooling (I just glued in a new fan to the old duct) , the benchy is a lot more wholesome . Still some shrinkage at the bow and overhangs are poor (needs more cooling ) . There's a bit of stringing - temperature?. Maybe a bit of under extrusion too (might be cooling , it is worse at the back side of the extruder) . Corners are a bit bulgy I may have to pick your brains about pressure advance etc. If you squint, you can just about make out something, something, benchy on the stern . base shows a little bit of curling, but the painted surface is not great for adhesion. |
