Original thread was here:
I can reproduce the lift seen in this video at time 1:35: [1drv.ms] manually by doing a tool change (T1) and then a move operation.
If I use Repetier host, and type in the following, it'll do the lift:
M104 T0 S195
M104 T1 S195
G92 E0 ; Reset extruder position
M109 T0 S195
M109 T1 S195

Repetier
Have a Kossel Mini with RAMPS 1.4 and Marlin; printing via Repetier host. I have successfully printed 2-color prints, but at the time the color change occurs (switch from E0 to E1) the printer Z lifts up about 5mm.
Here is the GCode at the time of the transition:
G1 X13.581 Y11.119 E12.71375
G1 X13.546 Y11.085 E12.71949
G1 F1800.000 E7.71949

Repetier
I had a STL (large one) that took 21 seconds to produce output in Cura, but took 735 minutes, 43 seconds in Slic3r. Yes, that's 12 hours. Ack. And, I did have it set to avoid crossing perimeters, but had the same setting in Cura as well. In certain cases, I really prefer the Slic3r output on the printer, but that amount of time to slice is ... well, long.

Fixed problem 1 with adjustment to speed in firmware.
Problem 2 is still there... (correction though:2) There is no movement in +Y or +X , but -Y and -X movements work fine. So, if the effector head is sitting at 0,0, it can move to -90,-90, and back to 0,0. But it cannot move to -90,-90. (or 0,-90 or -90,0)
Anyone?

I am building a Kossel Maxi – and just got the RAMPS board wired up and am doing my initial testing and calibrations (Marlin FW).
Found two odd behaviors that I’m seeking advice on:
1) Movement in Z up or down works fine using the control wheel in Repetier Host. If the printer is homed, hitting “home” again will do the little three-step re-home dance perfectly. However, if the printer’s

Agree with JMF here. I have some push-fits that have only 3 or 4 clamping "blades" in them that hold the PTFE tubing in place. The blades seem to break easily if the push-fit quality is questionable. Honestly, unless you're getting a good quality push-fit, consider these things consumables. Buy a few extra.
I can't speak to the ones with the Ebay link, but they look like the ones I use that

Going back to your original prints, to me, it looked like you were printing with too little filament. As already indicated, you'll need to ensure your extruder is calibrated (meaning when you tell the printer to feed 10mm of filament, the stepper actually feeds exactly 10mm) . And, you need to measure the diameter of your filament. Yes, I know it's supposed to be 1.75mm, but sometimes it's thi

@Shadow - I bought the geared motor as I was starting to get into 3D printers. So, it was more of a purchase under lack of information, rather than a specific need. That said, it works great. By tapered - like a sharpened pencil. Like Life cereal - "Hey Mikey, try it, you'll like it."

I am using the geared stepper motor and hobbed gear for my extruder setup. It's a NEMA 17 with a 5.18:1 gear drive. Works fine - no issues with pushing filament. I'm also using the E3D v6. I've tapered the end of the Teflon tube that is seated in the cold end, up against the heat break. It has fixed ALL of my jamming issues with the E3D. FWIW, I'm using the FSR's for bed leveling, and it wo

Suggestions for a good insulator between a heated bed and acrylic? I have a triangular piece of acrylic that sits over my aluminum extrusion frame with the FSR's sandwiched between the two. That part is working perfect with triggering the FSR's, and I have no need/desire to change it. But, I'd like to put a 170mm round heated glass build plate over top, and need to ensure I have sufficient ins

I'd be willing to try your Gcode to see if my printer does the same thing. I'm running a Marlin FW that supports FSRs, and have the RAMPs board too. Would be at least another data point if nothing else...

Love Cura. I went back to Slic3r for a trial print, and it killed me how long the slicing was (I waited almost 10 minutes before I just bailed). Same design sliced in Cura in < 10 seconds.
Repetier Host now supports Cura and offers printing profiles to be saved/selected. Perfect. Love it. And I agree, the print quality is much better from the Cura gcode. The only thing I miss is hex i

Ensure that your X, Y and Z endstops match the X, Y and Z motors. In other words, the X endstop should be on the same vertical extrusion as your X stepper and the same for Y and Z. If they're not matching, I've seen odd behavior like that.

Printing vases seem to have an odd problem on my Kossel Mini - there are tight corners in which the print head movement is very fast. It causes thin strands to form. I'm using Slic3r. The only setting that seems to make sense in terms of speed settings is "travel" (speed for non-print moves). But the vase still has material that should be in these locations.
Thoughts on how to correct this?

I've been using Repetier Host for my USB-based printing control. I have done several prints longer than 6 hours (mostly vases) without any problems.
I also have the same hardware/firmware and I use Slic3r for slicing.
Give it a try!

I have some paper "application tape" from my vinyl cutting process that I lay down on either acrylic or glass. It has a porous enough surface to take the PLA quite nicely.
Search GreenStar Layflat Classic Transfer Tape for the stuff I use. Way cheaper than blue tape, and easy to remove from the bed for changing.

It stairsteps upward when it thinks it's hit the probe point immediately upon moving downward towards the bed. In other words, your z probe is being "pressed" all the time. Set the Z_MIN_ENDSTOP_INVERTING to the opposite of what it is now and see if that fixes it. When its right, you should be able to send M119 to the printer and get:
06:39:28.542 : N9 M119 *3
06:39:28.545 : Reporting endstop

Having nearly the same issue with mine.
I had mine working well - then blew F2 fuse. Now, not working right on homing. But...
When it was - Autohome was just issuing a G28 (AFAIK). Each axis would return up, then trip the switches, and then move down about 5mm. They happened in succession, not simultaneously.
I know it's not the full answer you're looking for but maybe it'll help.

I have the same problem - But on a Kossel Mini with Sainsmart RAMPS 1.4 and Sainsmart Mega board. Configured the firmware with Repetier 0.91 v4. I do have an ATX computer power supply rated to 305W connected to both of my Power IN connections. I can manually enable the j-head cooling fan, the heat extruder, the heated printbed, and verify that all those are working.
