Hey guyz wanted to share a few pics of the QU-BD extruder being built and of it up and running. I have used most extruder's out there during my trials of 3D printing, with the last one being the MK7 Stepstruder from makerbot (which is what the QU-BD is based from) and I have to say this is the best one I have used so far! I have not had a lot of time for testing but right off the bat after the first few test extrudes I knew it was going to be a good one. I hope it works out to be a great extruder for us all to use, because the price is right and the parts are very well done. I am most happy to finally see it up and running after it took me so long to get around to building it This extruder like the rest, still leaves room for perfecting but thats the beauty of open sourcing it to everyone. It will just keep getting better! Hope this helps others with their QU-BD extruder builds Mark and Trish Attached files
Mark looks like you got this going really really well. By looking at your pics I think I know what may be wrong with mine. It would seem that one set of holes was drilled slightly off causing a kink in the filament. I will tear mine apart to verify if it was the drilling or something moving around again. anyway congrats on the working setup.
Glad to hear it Nick once you get this sorted out your going to love it Short video of the QU-BD in action Mark and Trish
That is great! I am with jovian, I think a handful of blocks are slightly off. No biggy cause like you say this is open source and can be farily easily improved upon. I have an ORD, and I love the way you mounted the extruder sideways. I am so gonna "borrow" that. What thermistor table did you use? The beta in the spec sheet has me worried a bit, my heart say epcos(1) but my head is saying honeywell(7) in Marlin.
You will want to use the 100K #1 So it should look like this' [pre]//=========================================================================== //=============================Thermal Settings ============================ //=========================================================================== //// Temperature sensor settings: // -2 is thermocouple with MAX6675 (only for sensor 0) // -1 is thermocouple with AD595 // 0 is not used // 1 is 100k thermistor // 2 is 200k thermistor // 3 is mendel-parts thermistor // 4 is 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !! // 5 is ParCan supplied 104GT-2 100K // 6 is EPCOS 100k // 7 is 100k Honeywell thermistor 135-104LAG-J01 #define TEMP_SENSOR_0 1 #define TEMP_SENSOR_1 0 #define TEMP_SENSOR_2 0 #define TEMP_SENSOR_BED 1[/pre] Hope this helps
Thanks again. I think the saying says you should follow your heart, so I will use your thermistor settings. I am only using one extruder right now, since I have the sanguinololu, so this is right up my alley. Plus that config lets me use a larger motor, with more torque. More Power Scotty! Sorry for the Star Trek Flashback, I need a vacation.
NP bro glad to see it could help. Let us know how you make out with yours (pics would be cool too ) We all need a good vacation! Mark and Trish
Cool I ordered a pair... I'm running a Wade style extruder and I'm not getting the results that I would like.. So time for direct extrusion. MATT
I haven't heard many good things about the filament drive gear on a Qu.bd unit. All the qu-bd swaps over on my side of the street have needed to go to a MBI unit especially at speed. (>100mm/sec) How are you guys dealing with this?
