I just borrowed an MKS board and loaded the firmware on it and it booted fine. It's something to do with the Mega 2560 and RAMPS 1.4 board combo.
-
Same results. Upload with #define DRV_TMC2130 uncommented and it will not reboot unless I jack around with the EXP2 cable unplugging it or moving it enough to break connection, but as soon as I comment out that line again and upload, it reboots and…

I'll try anything. I have multiple boards to work with so I don't have to worry about taking my machine down... when it actually runs lol. I'll let you know how it goes tomorrow. Thanks for your help and thanks for your patience while I work thro…

@alexsomesan So back to your post above, now that I know it's a TMC thing. This is all happening with just the RAMPS plugged into the Mega2560 and RRD full graphics smart controller. No stepper drivers, no temp sensors, no heater. It happens whi…

I am slowly rebuilding the firmware from scratch. I appears that when I enable pin D32 for my CS pin that is what is screwing up my firmware. I have verified that PIN 32 does NOT go to any of the LDC pins on my smart adapter so I have no clue why …
-
Well, I thought I figured it out, but now I don't know. I resoldered every single pin. Now I'm wondering if it's a pin issue in my pins file...
-
This is absolutely insane! Both of my RAMPS boards have back EXP2 solders. I wonder if 0.92 was not using the specific pin or maybe it did not need as much power. It's no wonder I had no issues from that one board, I must've had it in just the ri…

I'm trying to make it work and narrowing it down. On the original, if I had a SD card plugged in it would not boot, but once I pulled the SD card it booted fine then I could put the card back in and print. On the one I am currently working one I c…

Out of the 3 working Mega 2560 boards I had, only 1 worked every time I uploaded 1.0.x. That one just died. I think either the USB burnt out or the main chip fried. Had a power surge or something. I had a brand new Mega 2560 I just removed from …
-
Yep, that's what I changed from (default?) 100 mm/s to 150 mm/s and it makes no difference. It takes 20 seconds per tool change and the furthest distance is 73 mm on the diagonal from extruder 1 to extruder 4. At 150 mm/s that should take less tha…
-
Great info on the TMC2130s. I've had to slow my steppers way down because of skipping. I have pretty powerful 2 amp, 84 oz.in steppers and if the feedrate is higher than 80 or 100, they skip. If they are too high they just vibrate. So all you di…

lol as I said in my first post, facepalm >_

Just tried experimenting with several settings. I set #define ENDSTOP_X_BACK_ON_HOME 20 and the nozzle is now 30 mm to the right of the left edge of the print area. I set #define ENDSTOP_X_BACK_ON_HOME -40 and it just goes back to the usual spot …
-
I just tried that. After I home my x axis the nozzle ends up 10 mm over the bed. It goes to the left then once it homes 2 times it goes about 40 mm to the right. I want the nozzle to be 10 mm further to the left after homing so it is just on the …
-
I also have to set extruder_is_z_probe 1 or it doesn't work for me. But I can now home, probe and print. Time for more fine tuning. The hardest part is keeping these 4 extruders at the same height.
-
Ok I got the file that time. That was exactly what I needed! The firmware configuration tool was always setting ENDSTOP_PULLUP_Z_MIN to true, but yours was false. Once manually set in the Arduino IDE it is working as expected on my printer. Now …
-
It has nothing to do with the drivers, its my MEGA 2560, RAMPS and reprap discount full graphics smart controller. The only reason I mentioned the drivers was 0.92 did not have support for those drivers and I needed 1.0.2 working. When I upload fi…
-
There is no file attached. I PMed you my email if you need to send it that way.
-
@MartinH Can you post or send me your config.h? While I am up and running, doing a home all yields results that aren't quite right. When I print, the bed leveling does good, but if you are able to properly home all and bed level, I'd love to see …
-
And after disabling the z_min endstop, I am finally printing! I've got some modifications and bed size/position calibrations to do, but I'm printing! The first thing I notice is I cannot move my x/y as fast or it just sits there vibrating. I ha…
-
@Roko I did not realize that the z_probe_height I entered in the config.h was then put in the EEPROM on day 1 when I uploaded. I thought the firmware values were used until I manually put something in EEPROM. That was how the last firmware I used…
-
So I learned the hard way that unlike the old firmware I used , this firmware loads into EEPROM and the next time you load firmware the old EEPROM settings are still there from the last firmware upload. I have to disable EEPROM until I get the z o…
-
Well I figured out why 1.0.2 would not load. I had the SD card in when uploading the firmware. I removed the SD card and it works fine. I can insert the SD card and it reads fine after booting, but it will not boot with a SD card in the slot.
-
I just want to see if this thing prints right now so I turned off z probing and set my z offset to -0.10 so it will lower 0.1 mm after homing (at least that's what the other firmware does). I set the z offset then saved to eeprom and homed the z ax…
-
I never set anything in the EEPROM to begin with on Repetier, plus I did a Load f. EEPROM from the LCD also. Also when I go to move and choose Z fast, the min endstop says off even if the LED on the probe is on (triggered). If I disable z-probing …
-
I make all changes in config.h and upload. In Marlin I only edit the EEPROM after everything worked and I only edit z offset. Can you post your config.h so I can compare?
-
It is currently working on 1.0.1 as downloaded from the site, but when it boots it says 1.0.2. My main priority at this time is getting the z probe working.
-
I just tried those settings and get the same result. Even before with those set to 1 the probe had time to untrigger. After probing 2 times, the z axis lowered 42 mm without fail. I am currently starting the homing at 60 mm for this reason and am…
-
Thanks for the suggestion, but I tried that too. These are my current z-probe settings. // #################### Z-Probing ##################### #define Z_PROBE_Z_OFFSET 0#define Z_PROBE_Z_OFFSET_MODE 0#define UI_BED_COATING 0#define FEATURE_Z_PROB…
