i switched to bondtech bmgs and having looked back. So much better.by Qdeathstar - CoreXY Machines
Oth, after watching the video, it looks beefy. And you could make it BIG very easily.by Qdeathstar - CoreXY Machines
No, he is saying that extrusione that you machine yourself give a better result than conduit.by Qdeathstar - CoreXY Machines
Oh. You already built the Printer? Why not show a picture of the actual printer instead of a rendering?by Qdeathstar - CoreXY Machines
It is as important to cut the pipe precisely as it is to cut extrusion precisely.... i’m not sure the OD of emt conduit is consistent enough to give you good quality prints. But, i like the idea. Use IMC instead, more heavy, more better.by Qdeathstar - CoreXY Machines
i think your bed is slightly lower in the “rough” part, and the nozzle is getting dragged through the filament..by Qdeathstar - CoreXY Machines

Yes, the pump is silent (I used it on a water cooled block for a chimera a while ago)by Qdeathstar - CoreXY Machines
i’ve made some water cooling jackets for my v6s.. i think if i get my part cooling straight i can have an almost silent printer.by Qdeathstar - CoreXY Machines
I did not like the titan extruder, but maybe my expectations were too high. It feels a bit flimsy to me. I’m working on replacing that with a bondtech bmg... i’ve modeled my extruder mount and the two bags give me about 20mm more print space in x and y than the titan. they feel more chunky too (printed sls nylon vs injection molded abs).by Qdeathstar - CoreXY Machines
The DuetWifi makes your printer about 50 percent quieter right out the box because it drives the steppers better. It also has a snazzy web interface which means you’ll never have to use sd cards or tether to a pc....by Qdeathstar - CoreXY Machines

Quoteo_lampe Yes, the filament drive is the weak point right now. ( Or too strong, to be exact ) How would a belt-extruder look like?by Qdeathstar - Plastic Extruder Working Group
Olampe, I just saw this. Very interesting! I look forward to your experiments. My only concern is the increased risk of filament breakage with the reduced diameter.. maybe this is good case for a belt-extruder instead of hobbled teeth?by Qdeathstar - Plastic Extruder Working Group
I made mine with a drill press, it got the job done. All you have to do is lay out the drill holes, use a drill pinch to center tap and bobs your auntieby Qdeathstar - CoreXY Machines
You need 2” x 2” and 2” x 1.5”by Qdeathstar - CoreXY Machines
The aluminum tubing works great! I stole that idea from the digital dentist and It gives you the perfect spacing. I just wish I had of taken more of his advice and planned a bit better. My build size is a little less that I was hoping for (345 x 380 vs 400x400mm). And my steppers are stuck inside the chamber. Surely the next build can’t be too far awayby Qdeathstar - CoreXY Machines
ramps isn’t capable of driving most nema23 steppers. what current do the steppers require?by Qdeathstar - CoreXY Machines
bondtech qr.. best ever. I’m in the process of switching from titans to bmgs on direct extruder and i i looks forward to the more power.by Qdeathstar - CoreXY Machines
How do you plan to drive the steppers, do you already have drivers?by Qdeathstar - CoreXY Machines
As a build, nothing wrong with doing this route. It’s interesting and you’ll learn a lot. My comment wasn’t meant to be derogatory. A lot of people just by stuff nowadays. You’ve built it, and get credit just for that.by Qdeathstar - CoreXY Machines
There is a lot of flimsiness bakes into this design. Should makes calibration/commissioning fun. Can’t wait to see what your prints look likeby Qdeathstar - CoreXY Machines
Thanks. I’ve checked the alignment for my x rails and although it appears to be quite good, i think eventually i will replace the rails with 25mm wide rails (they are 10mm now) and i will mount them onto an aluminum backplate, instead of directly onto the extrusion. This should help insure everything (idler, motormount, and rail) is dead nuts on. We are in the process of moving so my mill is aby Qdeathstar - CoreXY Machines
Hey guys... This is the motor i am using for X and Y: I have the current set to 1500 in the duetWifi. The stepper does not appear to be getting hot. (which is strange, isn't it, since I'm close to the rated current?) Using a method that probably is invalid, it looks like it takes about 2.4kg of force to stall the motors. I used a fish scale attached to one side of the printer, and the otherby Qdeathstar - CoreXY Machines
I agree that the nozzle hitting plastic shouldn’t cause it to skip steps though, none my other printers did that... they would just knock the print off the build plate or gouge it...by Qdeathstar - CoreXY Machines
I am using the smaller stepper that e3d provides for the titan, so maybe that is not a pancake. For some reason they chose .09 degree steppers and afaik that generally is lower torque compared to a 1.8 degree motor and I doubt an extruder needs the extra resolution. As far as the backlash, here is a picture of the first layer (though it is being printed at about 30mm/s where as the second layeby Qdeathstar - CoreXY Machines
Yes, I am using the pancake motor, but I don’t think the motor is stalling.by Qdeathstar - CoreXY Machines
Yea, the temperature stayed pretty steady but I think the aero extruded just didn’t have enough torque to pull through .4mm of filament at 60mm/s I tried 40 mm/s and it got 4-5 layers deep before failure so I lowered it again to 30 mm/s and it seems to print fine 8 hours in. I didn’t hear any clicking from the extruded, so my guess is that the cog was just grinding on the filament slipping inby Qdeathstar - CoreXY Machines
Olampe, those are some great suggestions, i will give them a shot. i’m not sure how to tackle the backlash problem, everything feels pretty stiff.by Qdeathstar - CoreXY Machines
