The problem with your tape may be down to the quality of the tape. I used to use tape but had a bunch of problems. I now use PVA glue diluted with water, painted on the heated bed. Sticks really well, stops warping and pops off easily when the heated bed cools.by 3dkarma - Printing
@jinx, PM me your details and I'll send a roll to you. Can you print in 3mm? That's Sean's preferred size. @Sean - let me know the colour.by 3dkarma - General
Have you had a look at the g-code? Are you using a long USB cable (I've had one of these introduce errors in prints)?by 3dkarma - Reprappers
Reprappro extruders have a setup whereby the hot end is attached to the x carriage with a couple of screws with springs on them. Vertically, it's X-carriage - spring - extruder body. Height and separation between nozzles is adjusted by tightening / loosening individual screws. They get three individually-adjustable hot ends on a single x-carriage with this setup.by 3dkarma - Reprappers
PM me your details and I'll send you a roll of PLA. You'll need to let me know the diameter (1.75mm or 3mm) and what colour you'd like.by 3dkarma - General
I think you made PLA.by 3dkarma - Let's design something! (I've got an idea ...)
A bend in the z-axis rod should not cause your hot end to drag through the print and knock it off. It sounds more like an adhesion issue. If you have some masking tape / blue painter's tape lying about, try printing on a layer of that on top of the glass. If you've got some PVA glue, dilute it about 1:1 with water and paint it on the glass (my preferred solution). Movement in the z-axis is moby 3dkarma - Printing
100 celsius is very high for PLA on the print bed. 60 is a better bet. 220 is very high for PLA at the extruder. Print PLA at as low a temperature as you can. Try 185 and go up if you get skipping at the extruder. Calibrate your e steps per mm as per the reprap wiki calibration guide. Insufficient extrusion can cause delamination. To help prevent curling with PLA, paint your print bed witby 3dkarma - Printing
Can you provide more info about the issue? There are lots of people on here who will advise for free.by 3dkarma - Jobs for people with RepRap skills
If you're using a bowden extruder, friction can increase as z-height increases due to the curl of the tube, resulting in exactly what you see in the first picture. I had the same problem when I switched from a 0.5mm nozzle to 0.3mm - the increased pressure in the melt chamber was just enough to cause the extruder to skip at about 1cm high, but lower than that it was fine. This was fixed by loweby 3dkarma - Printing
Upvote for the dilute PVA method. This solved all my lifting / curling problems and is easy to apply.by 3dkarma - Printing
