Re: What Thermistor for Gen7 1.3.1 - 13 years ago

Hi, is it possible to use a 5kOhm (NTC) Typ M87 Epcos M87 = G 350 5 K -55 - +300 ºC on the Gen7 Board? Can I leave the resistors as they are or do I have to make some modifications? The reason is that conrad electronics discontinued my previous thermistor "Epcos M87 10k"... Thanks for your help...

Re: ReplicatorG 31 and + control panel issues with mendel driver - 13 years ago

I could take care of that as long as Im using replicatorg to drive my mendels... However, in RepG a lot of things are continuously rewritten, and hence are not working from release to release... So I would need to know which things are not working ... For now, Im focussed on systems using the RepRap5D driver. I'm also thinking about having a tool chain with teacup firmware, at least beeing teac

Re: ReplicatorG 31 and + control panel issues with mendel driver - 13 years ago

Hm, just created a linux (14mb) and windows (ca.56mb) version... Too large to send by mail :-( going to fork the repo now... Done... usage: git clone git://github.com/RobertFach/ReplicatorG.git then build the desired release using the scripts... instructions can be found on the RepG website Please let me know if it works for you - Just in case that I have forgotten something Cheers,

Re: teacup: y axis periodically looses steps at defined positions in upper layers - 13 years ago

I found the problem... and its neither RepG nor teacup firmware... it was a hardware defect, my y axis drive pulley was a bit loose... The reason why I suspected firmware or host is that I have replaced both a few days ago, however, as I already mentioned, I was unable to remember when it first occured. Hopefully this post might help other Reprappers when hitting strange problems. Cheers,

Re: ReplicatorG 31 and + control panel issues with mendel driver - 13 years ago

Hi, what machine profile are you using and which is the underlying driver? I guess its also the RepRap5D driver? I will check the extruder later on, as far as I remember, it never worked on my repg-0025 version. In order to get the patch, I could create a fork of the repository on github. I could also create a distribution of your choice downloadable as zip, tgz, or whatever. I would prefer th

teacup: y axis periodically looses steps at defined positions in upper layers - 13 years ago

Hi, I hit a very strange issue: When I print for example the 0.5mm calib. cube, the first layer is put in correct dimensions. However, as soon as my printer steps to the second layer, my y axis seems to loose steps at the same position all the time. This looks like a very short slow down of my y-axis movement when going from bottom to top, near the bottom, and another slowdown will occur when i

Re: ReplicatorG 31 control panel issues with mendel driver - 13 years ago

Hej, I jumped also to ReplicatorG 0034 Beta and with this jump, the control panel temperature readings and settings didn't work anymore. My firmware is a teacup which uses ReplicatorGs RepRap5D driver. I had a look at the code and fixed the "bugs" or better missing functions... It seems as there was a big code rewrite due to multi tool heads. Whatever, I have now a version where I can set the t

Woodstrap Mendel Timelapsed 3D printing movie - 13 years ago

Hi, this is a video showing my repstrap project. It's a woodstrap Mendel, which I built several months ago. I made everything on my own, the forum has been a great help - of course. This is the video: It shows the printer printing a part, I have timelapsed the whole printing time to 3.5 minutes... I have used that Mendel to Repstrap another Mendel... To summarize, I would like to thank all
