Hello, I got everything working finally, trying to calibrate the extrusion. My extruder is .35mm and when it extrude a single height, the thickness is on aveage 1.30mm. I'm sure this can be controlled by the extruder feed rate but changing the feed rate on the sprinter firmware doesn't seemed to reduce the thickness. Anyone know where else to look for, also what is the ideal thickness for .35mm to extrude, 35mm? I'm running sprinter firmware with pronterface and slic3r.

If you go with this hot end make sure it will fit your printer. It is shorter then a j head, i have my x rails set vertically amd had to modify my mountimg so the hotend could reach the bed before the x carriage hit the bed... but i designed and built my own printer.]]> cat.farmer RAMPS Electronics Fri, 24 Jan 2014 12:01:44 -0500 https://reprap.org/forum/read.php?219,294072,300412#msg-300412 https://reprap.org/forum/read.php?219,294072,300412#msg-300412 skangreprap RAMPS Electronics Fri, 24 Jan 2014 10:51:46 -0500 https://reprap.org/forum/read.php?219,294072,299554#msg-299554 https://reprap.org/forum/read.php?219,294072,299554#msg-299554 cat.farmer RAMPS Electronics Wed, 22 Jan 2014 21:49:17 -0500 https://reprap.org/forum/read.php?219,294072,299355#msg-299355 https://reprap.org/forum/read.php?219,294072,299355#msg-299355 skangreprap RAMPS Electronics Wed, 22 Jan 2014 13:44:05 -0500 https://reprap.org/forum/read.php?219,294072,299225#msg-299225 https://reprap.org/forum/read.php?219,294072,299225#msg-299225 cat.farmer RAMPS Electronics Wed, 22 Jan 2014 09:18:11 -0500 https://reprap.org/forum/read.php?219,294072,298724#msg-298724 https://reprap.org/forum/read.php?219,294072,298724#msg-298724 www.ebay.co.uk]
wades extruder
have played with temperature ranging from 180 - 230 celcius.
This is 3mm filament through 3mm extruder. the hole size is .35mm.
Using the default push speed on sprinter which is set to 1380 but I've also tried 800 - 1300 with mixed results.]]> skangreprap RAMPS Electronics Tue, 21 Jan 2014 12:42:38 -0500 https://reprap.org/forum/read.php?219,294072,296816#msg-296816 https://reprap.org/forum/read.php?219,294072,296816#msg-296816 What type of filamet?
What type of hotend?
Where did you buy the hotend?
What type of extruder?
What temp are you extruding at?
Are you trying to push 3mm filamet through a 1.75mm hotend?
How fast are you pushing the filamet?

It is posible you damaged the hotend having it that close to the bed. Or you could have hit a bad spot in your roll of filamet. Or the themister is gone bad and give incorrect heat readings..

I would not recommend. Widening the orifice, cleaning it.. maybe...but not widening no.]]> cat.farmer RAMPS Electronics Sat, 18 Jan 2014 00:25:20 -0500 https://reprap.org/forum/read.php?219,294072,296808#msg-296808 https://reprap.org/forum/read.php?219,294072,296808#msg-296808 I've tried tightening the tension screw and loosening it but the problem is more consistent now. When the extruder change speed from slow to fast, it gets jammed. When the extruder retract a 1mm it also jams.
Any ideas? I noticed when I put the 3mm filament in manually for the first run, it was really hard to push it in manually. Maybe I need to widen the extruder hole?]]> skangreprap RAMPS Electronics Fri, 17 Jan 2014 23:58:59 -0500 https://reprap.org/forum/read.php?219,294072,294659#msg-294659 https://reprap.org/forum/read.php?219,294072,294659#msg-294659 check your feed rate as Dust suggested.]]> cat.farmer RAMPS Electronics Tue, 14 Jan 2014 13:32:36 -0500 https://reprap.org/forum/read.php?219,294072,294358#msg-294358 https://reprap.org/forum/read.php?219,294072,294358#msg-294358
but slic3r commends what it should be in the top of the gcode file. Take a look at that

In saying that... unless you have a really small layer height.. that sound really wrong.
Check that you have a nozzle set to .35 on slic3r (will also be in gcode comments)

Then check you e-steps. Do the standard extrude 10mm. did your extruder take in 10mm?]]> Dust RAMPS Electronics Tue, 14 Jan 2014 04:16:30 -0500 https://reprap.org/forum/read.php?219,294072,294072#msg-294072 https://reprap.org/forum/read.php?219,294072,294072#msg-294072
