Is anyone else seeing issues with the crimp connections in the harnesses? I had one wire in the endstop harness that was crimped onto an unstripped wire, how it occassionally made contact is a mystery to me.

[url=http://Prusa i3 Build Tutorial : Part 11 - Calibrating the X ...]calibration[/url]
Ok another noobie question. I've got the kit all together and all my axis's home. What should be my next step? I know nothing about 3d printing. Should I calibrate my machine next? If so how do I go about that?
Should I used the link above?[/quote]
If all of your axis home correctly, and you have all of your steppers at the right steps/mm in marlin (remember to set your extruder's steps/mm), I would say the next step would be to level you bed, and then re-adjust the Z endstop. After that, I would say to conduct a small test print to make sure that all of your setting in marlin and rep-host are correct for printing, and to give you a idea of how you will need to adjust your temps. Also, make sure you calibrate you stepper motor's steps/mm using the [url=http://www.prusaprinters.org/calculator/#stepspermmbelt]Prusa calculator[/url], and not a "calibration cube". Calibration cubes do not give accurate steps/mm information.

I have been suspect that my extruder is not putting out enough filament to keep up with demand. So I wanted to calibrate it...I was following this guide.
[www.youtube.com]
I used Repetier to run out 100mm of filament I literally got about 30mm only. This seems crazy to me...could it really be off that much!?!?
I also noticed the filament did not run smoothly, it would stop, jump, slowdown, etc. I thought that the stepper motor might be skipping steps so I turned up the current using the pot on the Driver Board. Apparently I either went too far, or bend the pot or something…but the motor just stopped working. I swapped out the driver with another one and it ran, so I’m pretty sure I fried the driver. Unfortunately I only got 4 working ones from Folger so I’ve ordered more.
In the meantime, has anyone else run into this problem, or had the calibration so far off!?!? I’m getting poor prints and I’m sure it’s an Extruder problem. Is it worth simply replacing the Extruder with the MOD7 Extruder!?!?
Thanks,
Sonny

Pull your extruder apart and make sure the set screw is tight on the gear attached to the motor. Some people had them loose.

Wow, that makes since!!! I never thought of checking it....thanks!!! Is it worth grinding a flat on the shaft for the set screw!?!?

I don't like grinding stuff (permanent destruction) so I usually just use blue lock tite on that kind of thing

OK so I figured out why the filament is not coming out!!! The extruder motor is running backwards during the print! All the other times it is running normal! I am at a loss as to why it would run normal in manual but backwards during a print!

I'm not sure why but my extruder motor was running backwards as well, I simply flipped the connector on the Ramps and it's working fine, both in manual and print modes.

That seems very odd. Did yours run the correct direction when running manually? That is the part that confuses me. It runs the correct direction to home and in the manual functions. I figured that if I swapped the connection it would be running backwards for all that.

Anyone using simplify3d? If so any setup tips?
I do (and love it). What specific tips do you need?
Here are three off the top of my head
1. (this would work for any slicing program, but the folks at Simplify3d provided it to me). To deal with ooze during hotend heatup, use this gcode:
G1 X0 Y0 Z.35 F900;
G1 X25 Y0 Z.15 E5 F225;
G1 X25 Y25 Z5 F3600;

Good point...on the grinding stuff. The gear was tight, so I ran another check, still half the amount as requested. I pulled the Hot End (while still hot) and ran only filament through the extruder. It was off by about 5mm over a 50mm run. Did the math, made a few changes in the firmware and then did several 100mmm runs that came out right on the money!!! Reinstalled the Hot End and back to 50% or less. I watched the internal gear and it never stopped moving even when the filament did. Also found losts of filament grind in the extruder, so I'm sure the gear is simply grinding it away due to too much restriction. Going to tear the Hot End apart and see if it clogged or restricted!?!?
Thanks for all the advice...it is greatly appreciated.

Just setting up my S3D now. Did you put that gcode in s3d somewhere so it works with all your programs? if so can you share the steps on how you did that?

Edit Process Settings -> Scripts -> Starting Script. Put it after the G28. It will slowly move the nozzle along one axis, then extrude a little bit in the corner while moving, then move really fast to the center.

I have been looking hard at Simplify3D and was just curious if it is worth the $150 price tag. I see alot of nice prints from therippa that I can not do with the oem software or eather I am not using it to the full potential. I have been on s3d site and have been reading and watching videos. It looks very powerful and I am very tempted to make the purchase . I would like some openions from some of you guys who have alot more experiance and knowledge of 3d printing than I do. The mechanical part of this thing I can handle with no problem , the software that makes it all come togeather is what I am lacking in.
