Have a question?
Are there any restrictions to the SD cards?
I can't get my SD Card working. I have a Kingston 8GB microDS HC class4.
I don't see the Card on my PC connected to USB. And it seems that the config.txt isn't loaded.
Because the Network module and the Display aren't operating, too.
Now i started to change my old printer to Re-arm everything else is going quite ok. M80 command give me some kill switch message, but that not so big problem.
Biggest problem is i dont get my Inductive sensor working smoothie at all. My mechanical endstops work ok on x and y axles. But z axle induction probe not working. I attach that on 1.28 or 1.29 and try to use z azle min ja max slots on ramps. But i dont get any changes z endstop state on M119 gcode. My induction sensor works realy well on marlin firmware. I measured that induction sensor give 3.3volts positive on mainboard when not triggered and 0.2volts when triggered.
But i dont get any changes to firmware state.
I got mine today, 7€ customs due (nice that you did not send with UPS or DHL Express, they add a 10€ charge on top). I need some tome to install it on my Trium3D (another kickstarter) Thanks!
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.
Thanks that was very helpful
1st basic tests worked fine.
RRD Full Graphic Smart LCD: o.k
see more on https://blog.georgmill.de/2017/02/07/32-bit-3d-printerboard-re-arm/
It runs only Smoothieware ?
@ross placing I mean delivered package won't include a SD memory card.
@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.
@ross placing No.
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
The board arrived today. It looks nice and works ... well, I'll test it tomorrow ;-)
@Creator Thanks for that fine piece of hardware.
Backer #509 received my pledge board today in Alberta, Canada. Nice looking board, well done. Installing soon in my Robo3D Kickstarter edition!
Are the DipTrace design files for the board available now?
@John Gkatzias Yes, D4 pin at SERVOS header will be able to drive a DC12V fan with an external N-MOSFET attached.
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?
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?
Btw, I managed to sort the fan out, I'd forgotten to switch the fan module on in firmware *facepalms*
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.
Arrived just now - UK based. It looks awesome, will get to playing in a bit
I've got mine for Jan shipping. No movement yet but glad anyway.
Converting a wanhao i3 and two tevo tarantulas eventually :)
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
I received my January shipment, East Coast USA.
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
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...
@ 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
Sorry everyone, I meant Re-ARM not Re-RAMP in my previous messages.
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.
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.
still waiting for my tracking number :')
Got tracking number woohoo
Tight/won't fit with the Ethernet module.
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?
Rah shipping notificaton!
@Jon, thanks for the post, I've been champing at the bit to get my grubby paws on mine, good to know they're starting to ship.
I've written up my experience with installing the Re-ARM on my Mini Kossel: https://cobaltgriffonary.blogspot.ca/2017/01/re-arm-of-mini-kossel.html
I received a shipping notice.
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.
Also looking for an update on the Jan deliveries, I have to replace a mega2560 and really not looking to bother as I should have my boards soon?
Any update on when January tier rewards will ship?
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.
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.
