MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
first of all, thanks a lot for designing this printer! I have no prior experience to 3D printing, so I have used this printer as an introduction in how 3D printers work and it was really a lot of fun building it (pictures of the build to follow).
I have finished building the printer and got everything working smoothly so far and the first few prints come out quite nicely. I just was wondering about one thing and thought someone from the community might advise on this.
For the default feedrates I have currently the following settings:
Everything is working fine like this, however, if I increase the feedrate for the Z axis (as I thought that is really was quite slow) even to only 0.2 and test Z axis movement in prontrface, the motors start to jitter and I do not get any reliable movement of the axis anymore, i.e. sometimes it moves, sometimes it doesn't. My Vref for the DRV8825 steppers that I have is set to 0.05V, and I have already replaced the motors (I have the 5V version), as I thought they might be the issue, but to no effect. It does seem to me that even at a max feedrate of 0.2 the motors do not seem to have enough torque anymore to move the Z axis. Is this low feedrate of 0.15 normal and do other people experience the same? If not - does anybody have an idea of what the issue might be?
Thanks a a lot and thanks again very much for all the work Thorgal!
