Nice! Thanks! She'll be so thrilled. She found an old USB cam in a pile of scraps and wanted to use it.
-
Yea I figured out the G92 part. For z hop I would need to look closer at the gcode since Simplify 3D controls that and not firmware. I just need to make sure there is a E command after the last Z command. If so it is on a printing layer and not a…
-
Found it. In theory G92 Z40.150 should have told the printer that it was currently at Z40.150 without homing. That is if the printer was not in the middle of a z hop when the power went out.
-
I just went through this myself. It may be a little late for you but for future searchers, that servo uses pin D5 not pin D11. Make sure this is set on RADDS boards: #define SERVO0_PIN 5

I just came across this issue myself and did not want to order a new LCD since I had a spare A8 LCD. It took me a bit to get it working in 1.0.3, but it now works quite well. Here is what I did: For the wire, I am plugging into EXP1 BUT I had to r…

Rossini, thanks for posting this! I used the download files to make my own cable and get my Due, RADDS and RRD graphics controller working.
-
Found the extension board with 3 stepper slots. I'll figure out the display and get it ordered. Next I'll need to figure out SPI for the TMC drivers. As usual, you guys are awesome and I am glad I found you all.
-
I was reading about the bad RAMPS-FD on another thread. RADDS looks like my best option, but I'm worried about expandability. I've only seen a 2 driver expansion board and since I use 2 dirvers for z that leaves me with only 4 extruder drivers. I…
-
Yea I was looking at the 32 bit boards you support and it looks like I can use a Due and RAMPS-FD or RADDS. I really wanted the Duet because of the pure awesomeness, but cannot use Repetier and I really don't want to change firmware since Repetier …

Ok looks like it’s a limitation of my board. I guess the calculations for a corexy is just too much for my 8 bit board. Looking into a better board.
-
That would be ENDSTOP_X_BACK_MOVE 5, correct? HOMING_ORDER HOME_ORDER_XYTZ works for me. Thanks! I just printed my first successful thing from my corexy! Homing in the center of the bed fixed all my z probe issues so far. Because I home x on th…
-
Thanks! I’ll try that when I get home. I did have issues with home order when I first set this up. Not sure why though. It’s a corexy if that matters.
-
Thanks. I actually just got brave enough to do this and it works exactly how I need. Slicer retracts the current tool 9 mm then G10 retracts all tools 2 mm more. That little bit on the other 4 tools was just enough to cause some ooze. No more st…
-
Dual Z is easy, but I'm trying to get the TMC support for the Z2 CS pin for SPI support. I've got 2 Z drivers now, but they are just regular A4988 drivers.
-
@alexsomesan The new one did not work either. It's something in the combo of the Mega 2560 and RRDFGSC. I now have a spare. Can I ship it to you so this can be figured out? I know I can't be the only person that will come across this.
-
I just ordered a new Arduino Mega, RAMPS 1.6 and RRDFGSC. If it does the same thing, I don't know what to do. @alexsomesan If you have not gotten one yet, what can I do to help out? I love this firmware and do NOT want to have to switch back to …
-
Well I'm back. For some reason it never quite worked right and I thought it was because I added more TMC drivers. I've unplugged everything except the heaters because they are not running and are not even close to my EXP2 cable and I have no drive…
-
The cs will not make a difference. It’s the 3 spi pins/wires that are doing it. How do you have the sd card wired to the spi with your TMC drivers? Pics?
-
Are you using the stock short cable? I made a longer custom cable and had to cut it shorter until I could read the card. The SPI is shared between the TMCs and SD reader and it does affect the sd reader. I’ve had to move all cables away from step…
-
Nope. Every tool change is the same. I used the diagonal as it is the longest distance and should only take a second or two where the other 2 should be faster. But S3D does the toolchange really fast.
-
alexsomesan said: I DO NOT RECOMMEND THIS SETUP ANYMORE! I have had countless random errors communicating with the drivers. Sometimes they'd all work fine, other times some drivers would return bogus values. There seemed to be no pattern to the er…
-
Yea I've been racking my brain but then realized that the slicer looks ahead when it does the toolchange, extruder 2 goes directly where it needs to print while the firmware cannot do look ahead and extruder 2 goes where extruder 1 was then goes to …
-
Here are the sample gcode. Let me know if you need me to send my firmware or config.h file. The line ; process Process2 is where the toolchange starts in both files. This is the gcode without the Simplify 3D offsets and the actual offsets are in …
-
I just moved all my offsets to Simplify 3D and it is doing fine. I do not like doing it that way because the preview is all wacky. I'm going to finish this print (offset calibration cube) so I can get the measurments then I'll grab a tool change p…
-
Another thing I noticed is when I told the printer to print only from extruder 2 it did the same thing. Once everything was heated the carriage very slowly moved left until extruder 2 is exactly where extruder 1 was then it starts moving at normal …
-
I just got the printer working again and am back to this issue. This printer did have Marlin on it and it did the tool switching quite fast. I am using Simplify 3D and there are no offsets set in there and there are no tool change scripts set. I …
-
Ok that makes sense why one worked on USB and the other did not. I installed a 1A regulator on the test one after it blew a month ago. These things are super sensitive and the crap drivers that came with one of the kits all failed within a couple …
-
Hitting the reset button is just like uploading new firmware. It just sits there locked up till I unplug the cable and plug it back in. I set this in the SDCard.cpp "HAL::delayMilliseconds(100); // wait for stabilization of contacts, bootup ..." a…
-
Just so you know, I do not have any drivers plugged into this one when powering on. It does not matter whether the TMC drivers are plugged in or not. I don't know if I'm just off base, but it looks like the Mega 2560 has SPI issues with SD cards a…

I bought a couple of kits. This was the other one made in China instead of Italy. https://www.amazon.com/gp/product/B071YV3FCL/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
