We've had a lot of success printing, but lately we've realized that the thicker/larger pieces have warping at the bed. At first I thought it was just ABS, but now I'm seeing we have the same issue with PLA. I first noticed that we had an issue when I tried printing an ABS item that was perhaps 4"x3"x3mm at the base and then some more material around the edges up to about 3/4". I made some prby cstelter - General Mendel Topics
Quotedc42 I have seen a fruit dessicator recommended for drying filament, but I don't have one. I may cut off a few meters and give this a try. We just happen to own a fruit dehydrator. Thanks for the suggestion.by cstelter - Printing
QuoteVDX ... an airtight box with desiccant for storing filament is sure a good idea ... regardless of the material For drying old filament you can temper it at a safe temperature (maybe 60degC for PVA?) for some hours ... Sounds like a plan. I had bought a bunch of these ziplock vacuum seal bags to help put some of my mother's belongings into storage when she downsized and have a few left ovby cstelter - Printing
Hi All, My son put his graduation money toward a 3D printer this summer, but he suffers from some learning disabilities so Dad (me) has the fun of building/maintaining/figuring out what can and can't be done so he can print the items he finds on thingiverse/wherever. I'm not complaining-- I find it far more enjoyable than I thought I would going in (and I knew I would enjoy it-- just not thisby cstelter - Printing
Quotedc42 I think that T-1 would work using my fork of RepRapFirmware as long as you don't have any commands in your tfree0.g or tfree1.g files. If you want to try my fork, you can download it by going to and clicking on the Raw button. If instead you want support on the official RepRapFirmware release, then I suggest you post this question on the Mendel or the Ormerod forum, where RepRapPro staby cstelter - Reprappers
T-1 does not work for me. On initial boot up, homex and homeall both work fine with T-1. However, if I cancel a print while T2 or T1 is in use, homeall and homex do not seem to fully run. I'm using the web interface. After the first press the Home X, Y, and Z all go orange so the T-1 seems to do something, but the motors don't move. It occurs to me now that perhaps the temps were tyring to aby cstelter - Reprappers
The machine recognized the M208 command which was great. Thank you again I added the two M208 commands right after the tool defs and G10 commands in config.g. It was not clear if this was wise or correct or not, but it seems to be working. This led to a cascade of changes because I then adjusted the 0,0 position on the plate which caused changes in homex and homey. But homez finds the whiteby cstelter - Reprappers
I appreciate the timely response! I only skimmed your reply but the key point I gathered is that the machine has its own built-in axis safety limits and i have to extend them in some particular way to account for the offsets. I've already applied the G10 offsets as you mention and my datum would be the first nozzle (on left when looking at the X axis with 0 to the left). Sounds like using poby cstelter - Reprappers
Hi All, I've *almost* got things working. I was able to print 2 color dice using a Tricolor Mendel-3 (duet electronics, latest firmware). I set G10 XNN YNN commands in my config.g file and that seemed to allow me to calibrate the heads to the same origin. My problem now is that I have 3 colors on the extruders and I want to print an STL on extruder 3 (happens to be blue). My X offset foby cstelter - Reprappers
