UPDATE: I have isolated this to the Extruder 1 stepper motor. As mentioned before this mostly happen when well into a print. All help appreciated.by sfinke - Printing
Only thing to bear in mind is the lower the nozzle temperature the less strength your part will have. That may or may not matter to you. Also the glass temperautre of ABS is around 105° dropping your nozzle temp from, say, 220° to 200° isn't going to help much with warping. Best thing, as already suggested, is to enclose the printer and keep the chamber hot.by sfinke - Printing
See the attached photo. Near the top is a missing layer. These occur at any height, although mostly nearer the top. The next layer was fine again. Really can't figure this out.by sfinke - Printing
Thanks for the input. I have tried so many things now. Gettting really frustrating. I don't know the first thing about adjusting motor current. How do I do this?by sfinke - Printing
Found the default e-steps: 92.65. And I found that Creality have indeed locked the firmware so I am unable to update it. Not a train smash as I can just add the compensation to the start g-code. Only thing I am not quite sure of is how to set different e-steps for each extruder using M92. My understanding is that M92 is modal, meaning that consequent M92's will overwrite previous ones.

I bought a Creality CR-X some weeks back. At first it ran really well. Recently though some issues have cropped up that have me stumped, specifically the skipping extruder steppers. For those that don't know the CR-X has two extruder steppers feeding into one nozzle. Out the box it actually working really well but I decided to tinker with things to try and get it even better.

This is definitely a CAD export issue. Look for facet settings, resolution, facet angle, something along those lines. 3D printers are essentially 2 1/2 axis cnc machines so yes they can read G2/G3 codes, otherwise your program would become prohibitively long and take longer to slice.by sfinke - Slic3r
Hope to revisit the Slic3r calibration this weekend...by sfinke - Slic3r
A very interesting discussion. Thanks to all!by sfinke - Slic3r
Downloading 1.2.9 and will try again (after many months...)by sfinke - Slic3r
Quotemoheshmohan Ok now finally i got some time to write about the work on my blog. Read it here Terminator Usb powered desktop toy Awesome Thanks!by sfinke - Look what I made!
Here are some results of last night's efforts: On the left is a solid 20x20x10 calibration cube; on the right is a single shell calibration piece as per the Slic3r extruder calibration method. Both were sliced by Slic3r. All relevant setting were filled in as required. All extrusion diameters were set to 0.4mm. I then printed the single shell item. Shell thickness cam out at exactly 0.4mm.

QuoteIMBoring25 It would seem the same approach could still be used. 95% scale of 106% scale is 100.7% scale. Awesome. Thanks.by sfinke - Slic3r
Thanks Alan. I think I wasn't clear enough in my post. I don't want to scale to 0.7% but rather increased by 0.7% (the shrinkage for ABS is 0.7% btw) so I want to enter 100.7 into the scale window...by sfinke - Slic3r
Quoteelwood127 I printed him at half scale and added the led eyes. My kid loved it. Thanks for the link. Did you sand it or anything before painting?by sfinke - Look what I made!
Thanks, Dave. I'll try that. What do you set as extrusion multiplier then?by sfinke - Slic3r
I calibrated slic3r yesterday as per these instructions. Worked exactly as explained and I thought I'd try a test print (the octopus from thingiverse). Printing at 1 shell I noticed there were holes. A results of under-extrusion? I only let it print for about 3-4mm then cancelled the print. The measured shell thickness was now 0.22mm, whereas after the calibration it measured 0.4mm. What happenedby sfinke - Slic3r
I can't figure out how to scale an item in Slic3r by a decimal amount like, say, 0.7%. The scale box only seems to allow increments of one. And yes, I know i can scale the model in the CAD software but want to know if its possible to do in Slic3r. Cheers.by sfinke - Slic3r
Having some difficulty calibrating my extruder with Slic3r. An extrusion multiplier of 90 results in massive over-extrusion while 86 under-extrudes so much that there are holes in the shell and gaps in the horizontal surfaces. Yes, I know I should try 88 and I will once I get some time but I was wondering if anyone here could chime in. The model is a simple 20x20x10 calibration block. Material:by sfinke - Slic3r
Quotedc42 I just downloaded and installed slic3r 1.2.7 (Windows x64 version) and immediately hit a bug. I press Help and then About sli3r, and the version information box comes up. But I can find no way to dismiss the box or do anything useful after that. I have to terminate the process using Task Manager. Confirmed.by sfinke - Slic3r
Quoteroboprint Try Slic3r 1.2.7 Thanks. Must have just been released. I didn't see it when I downloaded 1.2.6. I'll check it out.by sfinke - Slic3r
Quotetadawson More likely because you are running windows. It's really hard to build a stable structure on soft mud . . . . - Tim That is a completely unhelpful post.by sfinke - Slic3r
Just realised I gave scant information. So to rectify: Slicer 1.2.6 Windows 7 Pro The crashes are random to my eyes. They occur when I import an stl, change settings, export a file or just have slicer open while I finish a quick game of solitaire. I should also mention that I have been able to export gcode files without issues too. Could it be the fact that I am using the beta? Thanks.by sfinke - Slic3r
Hi, I get slicer crashing/closing almost every time I try to use it. Usually it just closes without warnign or fanfare but twice i got this error message: Problem Event Name: APPCRASH Application Name: slic3r.exe Application Version: 1.2.6.77 Application Timestamp: 503fe786 Fault Module Name: perl514.dll Fault Module Version: 0.0.0.0 Fault Module Timestamp: 4f85cd47 Exception Codeby sfinke - Slic3r
