Well, I finally got enough parts in to start assembly. Now my biggest challenge is building the build platform. If you have any suggestions I'd like to hear them. Thanks a bunch! Clayby t357 - Reprappers
I'm using this driver which says it supports up to 2 amps and up to 35 volts max (with additional cooling). Its typical to use NEMA 17 motors with these drivers but I would like to run one axis of a 3d printer using a NEMA 23 motor so I can get higher torque. The problem is that I don't know enough about steppers to know what is good and what is bad. I need it to run fairly cool as they are mby t357 - Controllers
Would it be possible to have dual stepper motors on the Y axis? am putting together a larger mendelmax with a 300x300 mm build platform and am concerned about wait. One option would be to build a super light weight, but expensive heated build platform. The ther is increasing the power available to move the Y axis. Would it be possible to run two nema 17 motors on the Y axis? What issues would I hby t357 - Controllers
I just thought I'd point you guys towards my build blog. I've been interested in RepRap since 2007 but just recently started back into it again. My project is a MendelMax that is scaled to a print area of 305mm x 305mm on the x an y axis. I'm trying to document it well so that others can use it as a basis for creating a slightly larger mendel max. Thanks to the support from this forum and the Mby t357 - Reprappers
I have been doing a lot of planning for the reprap I am building and had a thought about a 4th axis on the reprap that would allow you to make perfectly round objects. it would require a head and tailstock aligned in the x axis and some type of mandrel, either glass or your print material which would be rotated by another stepper motor. I'm wondering, do you think that this ability would be ofby t357 - Mechanics
Just a thought, maybe you could fill the canister with argon gas and then pull filament from the top. The argon gas would displace the air in the canister and is heavier than air and wouldn't be readily lost.by t357 - Printing
I've just starting to purchase parts to build up a mendelmax and I've been doing a lot of research on using PVA as a support material. It seems like a lot of people have been having issues with the PVA absorbing humidity rapidly and making it impossible to print. What if you were to build a sealed case for the roll, and either integrate some type of electrical dehumidifier or purge the case witby t357 - Printing
