I have recently been playing around with a spool of PETG from rigidInk. Attached is a side by side of two test cubes with different minimum layer times, all other settings the same. The left cube has no minimum layer time and printed in about 3 minutes excluding warm up time, whilst the right hand cube had a minimum 15 second layer time and took a total of 8 minutes. The left hand cube retained hby alkempster - Printing
i have been interested in the lyman extruder for a while, just can't find all of the parts in the UK:by alkempster - Plastic Extruder Working Group
I think you have misread... ID relates to the inside hole diameter and OD is the outsiide diameter (how big overall): 3.0mm - 4mm ID 6mm OD for 3mm filament - inner diameter of 4mm and an outer diameter of 6mm 1.75mm - 2mm ID 4mm OD for 1.75mm filament - inner diameter of 2mm and an outer diameter of 4mm hope this helps!by alkempster - Mendel90
I personally have the 1.75mm fitted to my mendel 90. You can do a swap but: - the print cooling fan will not fit ( i think someone has resolved this: ) - the E3D fan duct was mounted to the right (from looking at the front), which just fits if the wingnut is placed with the wings front to back - you will loose some z height - i opted to increase the filament path diameter of the wades block to 4by alkempster - Mendel90
Sometimes strain is put on the wires by making them too short. My thought in adding strain relief near to the connectors is for two reasons: it will limit the amount of wire that could be put under tension, and, should any connection become loose, would hold the wire into the connector preventing shorts (although not this specific problem). It could also have the benefit of making wiring easier.by alkempster - Mendel90
adding strain relief to the wires may help to prevent this from occuring in the futureby alkempster - Mendel90
the rubber is the base material, my belts are steel reinforced and they work greatby alkempster - General
hi nophead, i believe it should be set and forget. I couldnt tighten the base bolt enough without damaging the dibond sheet, i think this caused the pulley to loose tension over time. The modified design gets around this by not needing to compress the sheet to get a good grip and without having to drill new holes to support the modification. How tight do you bolt yours to the frame? @neildarlowby alkempster - Mendel90
I really like nopheads design and its implementation. However, i kept having trouble keeping tension on the y axis timing belt. Not really wanting to drill a load of new holes i set about creating a modified y idler and created: This idler is a two part design the axle part uses most of the original design but removes the nut trap and adds two wings with M4 captive nuts.
