      Got someone a config for me for a core xy?
      I tryed many things but the axis moves where ever they want and my Bed Temperature ist
      constant on -25°C ... I'am not living in a Freezer. :D

      Thanks Roy, board is arrived today. Not have time to start installing that now. But want to ask Roy @Roy Cortes or @all are they some tested or best microsd cards to that use. microsd card is needed to change and do settings on firmware on smoothieware if i am right?

      I dont use microsd anything else only that firmware settings. I use octoprint to do all printings.

      @all
      1st basic tests worked fine.
      Ethernet: o.k.
      RRD Full Graphic Smart LCD: o.k

      It runs only Smoothieware ?

      @John Gkatzias You may find a clue for DIY Cooling Fan MOSFET Driver at http://www.thingiverse.com/thing:22202 And, RepRapDiscount has RepRap Ramps 1.4 Fan Extender http://www.reprapdiscount.com/electronics/25-reprap-ramps-14-fan-extender.html At least 1 of 2 fans will work. Try online searching "RAMPS fan MOSFET" if you want more info.

      It would be nice that someone who knows what he is doing makes a how to guide about that external mosfet.

      question, should the rearm boards have a tf memory card with them?

      backer 201, australia, just received the boards, they look very good, will get around to the upgrading in the next week or so, btw tracking still shows in los angles

    11. Georg Mill on February 7, 2017

      The board arrived today. It looks nice and works ... well, I'll test it tomorrow ;-)

      Are the DipTrace design files for the board available now?

      Hideo Kobayashi on February 5, 2017

      @John Gkatzias Yes, D4 pin at SERVOS header will be able to drive a DC12V fan with an external N-MOSFET attached.

      @Hideo Kobayashi
      Do you mean that it could work as a setup with two extruders, a heated bed and a cooling fan for the printed part?

      Anyone else having issues with thermister reading INF right across the board?
      M105: ok T:inf /0.0 @0 T:inf /0.0 @0 T:inf /0.0 @0

      Using pin 0.23 0.25 and 0.24 for T1 T2 and T3 (extruder bed extruder)
      Tested the resistance across T1 T2 and T3 on the pins on the side of the rearm and get 44.5k resistance right across so they do seem to be connceted!

      ive got RRD cables coming for mine, has anyone got any experience with OLED panels?

      Y on February 2, 2017

      Seems I incorrectly responded to the survey specifying other and missing the RRD display So no cable for me :(

      Is there a way to get the modified cable? or what is required to splice it myself?

    19. Ax Smith-Laffin on February 2, 2017

      Btw, I managed to sort the fan out, I'd forgotten to switch the fan module on in firmware *facepalms*

    20. Ax Smith-Laffin on January 31, 2017

      Right been playing and I've got an issue with the layer fan. Fan has been tested as working, it's 5v shifted voltage on the Re-ARM on pin 2.4 but I'm guessing it's a knock off 'fet so the gate voltage is too high. Will replace it and see what happens.

    21. Ax Smith-Laffin on January 31, 2017

      Arrived just now - UK based. It looks awesome, will get to playing in a bit

      Hi. Seems like people are getting shipping notifications now - whew - didn't get my notification yet, at least this means all hope is not lost! (I'm still waiting for the Plastc card I backed two years ago! Lol

      received my shipping notice, now just waiting, and WHEN I get the re-arms I will start converting three printers a kc, robblebot basic, and a prussa i3 clone, as my diamond headed printer is on a rambo, it will not be converted

      Hideo Kobayashi on January 27, 2017

      I figure out that Re-ARM can swing full of MOS-FET inputs (5V level each on genuine RAMPS) using quad level converter MC74VHCT125A (14 pin device marked U2 on prototype, U1 on delivered board). Three channels are dedicated to drive MOS-FET, rest one channel seems connected with one of SERVOS header pins, D4.

      Received my shipping notice yesterday afternoon. Now to decide which printer the Re-Arm with grace...

      Jan delivery and no updates/shipping notices yet...

    29. Jon Raymond on January 26, 2017

      @ Don Atwood
      It's possible that your RAMPS board has the heated bed issue because the gate voltage for the mosfet is too high for the 3.3v logic of the Re-Arm. This would explain why the 5v level of the Mega board is able to turn the bed on while the Re-Arm won't.

      I'm in the January deliveries and received shipping notice yesterday

      Quick update

      I switched to a new RAMPS board and now the heated bed does seem to work. Don't understand why the first RAMPS board works with Arduino but not RAMPS, but the new board is working as expected. Sorry for any inconvenience. Will let you know if I figure out why old RAMPS board was not working with Re-RAMPS.

      Thanks

      Received Re-RAMP board in December as promised. Using Jim Wagner config file as well as the example from Roy Cortes I have everything working except the heated bed. Using 12V input to both the power in lugs on the RAMP V1.4 board. LEDs light for fan and extruder (as well as voltage on the output plugs). But no LED or voltage on D8 for heated bed. Have tried bang-bang and PID settings. Using pin P2.7 for the output pin. Any ideas of what else to test? Everything works including heated bed with Arduino/RAMPS setup using the same RAMPS board.

      Thx Don

      No shipping notice yet but I'll recheck tonight.

      Has anyone seen or designed a case to print for these yet ? I assume some mega2560 cases would be too tight?

      It is not to late to cancel the credit card payment.
      Just tell them you never received anything and they will put your payment on hold until the other side can prove different.

      I copied the config, loaded my values and the LCD won't work and I can't seem to get this up and running. Not sure what the issue is now so I opened a support ticket on the panucatt site.

      Hi there,
      I just startet building a Kossel mini printer.
      I am on the January batch in germany.
      How long do you guys think, it will take until the january rewards are on their way ?
      I do not want to fight with Marlin and the getting my Re-Arm Board to start all over again with smoothieware then.

      @Roy
      thank you for this great board. simply followed the provided descriptions, changed my machine specific values, calibrated (manually), and now my (scaled) kossel runs a lot smoother, faster and without missing steps. awesome!

    48. Benoit Miller on January 18, 2017

      @Mark, on Smoothie the CoreXY support is not much more than adding "arm_solution corexy" to your config file, the rest is pretty much machine-specific :)

      Still, you can find my config here if you like: https://github.com/mzbotreprap/VORON/tree/master/Firmware/Smoothieware/Re-ARM

      I posted about my upgrade experience on Reddit: https://www.reddit.com/r/voroncorexy/comments/5n1xen/rearm_ramps14sb_voron_first_impressions/
