    • RE: PanelDue V.2 Layout and Cabling.

      Why that's just an awesome solution! Can you hear my hand smack my forehead from there? Yes I used an ide cable with the existing female 40 pin connector and put the wurth 40pin male connector on the other end. And thanks for the heads up on reversing the connector direction so as to not have to swap the wires in the harness.

      Best Regards,
      Matt.

    • PanelDue V.2 Layout and Cabling.

      Howdy Folks,
      Does anyone know a part number for an FCI cable mounted pin header that would let me extend the PanelDue V.2 back away from the LCD connection? I used Wurth #61204025821 and it works after a fashion but the 5 pin right angle header is snuggled right up against the socket on the board and this required me to butcher my Wurth header clamp and shroud to get it to fit. It would be really nice if that 5 pin header were to be moved farther down the board in the next iteration

      Best Regards,
      Matt.

    • RE: Motor idle noise ?

      @dc42:

      What is the inductance of the noisy motors, and what current do you run them at?

      9.3mH, 750mA, and 5.75 Ohms/phase, 1.8 degree/step on the X and Y motors. Just standard FlashForge steppers.

    • RE: Need help with getting prints to not crash

      What is your printer? Try putting in nothing more than G28 in your start script. You will then have to set the temperatures from the web interface. Note that when you change the process the profile will change to "modified" and in order to save it you must click update profile or save as new. My start script is specific to my machine/process. Also you can write gcode commands for moving, priming, and wiping the nozzle as well as setting the center of the build plate. Look at what G92 does.

      Check what is being written under the "scripts" tab for the "Process" in S3D. I had to write an entirely new script for mine.

    • RE: Motor idle noise ?

      I've heard a noise not unlike this as well. When I was jogging the the x/y carriage and z axis around for bed leveling, ever so often I would hear it whining at me. I could jog the y or x or z and it might go away. When printing I really couldn't hear it. Following this post because I'm curious. FFCP/DuetWiFi.

    • RE: Production Duet Ethernet pictures

      Excellent work! I love my WiFi but I would rather have the Ethernet. I will most likely purchase another Duet but of the Ethernet flavor. If the Ethernet module ever becomes available I would be interested in it, my soldering skills are up to the task of removal and mounting.

    • RE: New Build! Want input!!!

      [q. "I planned on trying to hack an inkjet to try to work, the viscosity of the thermoplastic concerned me. I was going to take a shortcut and copy/modify Stratasys's Liquifier pump first as I really would not have to change that much, my first thought was a high temp peristaltic pump."…

      "Precison is MY current problem, My Kossel Mini works, however, I cannot really create too many function parts to my standards...which may be a tad ambitious."

      Inkjet/Polyjet does not use Themoplastic. It uses UV curable polymers. These polymers can be really "nasty" to work with, they also can be prohibitively expensive. The design paradigm of the multifab was based on the openfab machine. The problem with having a machine that will do both cnc machining and printing is that for the printing you want low mass in the head and gantry with high acceleration movements and for machining you need high mass low acceleration for holding any kind of tolerance in the part. I don't believe a multi-machine utilizing the same gantry for both processes will ever be a valid solution. Next, when you finish comprehending Miss Kwans thesis on inkjet drive electronics you will find a few more problems. Hacking the Drop on Demand (DoD) control of the Epson inkjet heads is a real pita! I began to see that the Multifab was really a frankenprinter that many students at csail under the guidance of Matusik had used to write and prove their thesis and was not ever really a finished product that could be built for $10k; the head used in the 2013 thesis is not even available anymore.

    • RE: New Build! Want input!!!

      Multifab has a problem, several in fact. I agree with you that we should have an inkjet printer for the hobbyist that isn't priced beyond the realm of reason. I've been working from the Multifab specs for a little over two years now. Precision is not the problem.
