Bump - Is the fact that the bed temp has dropped a clue ??? Is the "thermal runaway" detector seeing a temp "drop" as a fault ?? Daveby softfoot - Printing
Hi, I have been running Marlin v2.0.x for some time without problems using PLA+ Recently, I switched to ABS and have printed several pieces without problem (they have all been about 20mm high) but now I am trying to print something 35mm high and it keeps reporting "bed thermal runaway" at various stages all about 15-20mm above the bed. The piece is a simple 50% fill cylinder 20mm diameter and 3by softfoot - Printing
I used two of the ports - one driving a vac pump the other a solonoid valve. The two loads had a fast diode across the pins the protect from back emf. It worked very well. Daveby softfoot - RAMPS Electronics
That did the trick but on my ATMEGA2560 based printer it left 742 bytes of RAM - so I reduced "SDSORT_LIMIT" from 40 to 20 as I dont keep many files on the SDCard, that gave me 1564 bytes of RAM. Thanks for the help. Dave [email protected] It may be reading the SD card each time you click which will noticeably slow things down. Try enabling the following.

That sounds more promising - I'll give that a try. Bobby softfoot - Firmware - Marlin
Hmmm, I'll give it a try but I suspect that will affect all the other menus as well. It is only one menu that is slow - when brousing the SD card for a file to print - the rest are OK. Daveby softfoot - Firmware - Marlin
When controlling my printer from the LCD encoder I find that in all of the menus (bar one) the movement of the highlighted line is responsive. However, in the "file to print" menu it is a lot slower and that is with only 3 file entries on the SD card --- to the extent that it feels like I didnt move the encoder knob and do it again only to find it moves on twice, it's just slow. Is there anywaby softfoot - Firmware - Marlin
I have a "Geetech i3 Pro C" fitted with a "FYSETC_MINI_12864_2_1" control panel. I have enabled the "NEOPIXEL_STARTUP_TEST" option and it correctly cycles through the colors at bootup. I have also enabled the "LED_CONTROL_MENU" option and the "lights" menus correctly appear --- but while the menus run they do not change the LEDs at all. What am I missing ?? My config files are attached. Daveby softfoot - Firmware - Marlin
I have a Geeetech i3 Pro C (acrylic) - and yes I have a 3dtouch rather than a bltouch, but it has proved to produce consistant measurements YMMV. However, I have been struggling for a long time to get bilinear leveling to work. There is no detectable twist in the x-axis and the 3dtouch has zero y axis offset to the nozzle, the bed is reasonably level by the "paper" test, and the printer printsby softfoot - Firmware - Marlin
Hi, I gather that there is a feature to allow compensation for a twist in the "X" axis in the latest release of Marlin ... Is there any documentation on using this especially regarding the "Wizard" ??? How well does it work?? I am rather loath to upgrade to this version unless the mechanism is effective as otherwise my printer is working well. I am very keen to try this but so far all I have fby softfoot - Firmware - Marlin

Hi, I have an application for a RAMPS 1.4 board to which it seems idealy suited. One part of the project has a need to control a small DC vacuum pump and I was thinking about using a relay driven from an IO pin, but I wondered if one of the heater ports could be used. The motor only takes about 0.5A and being an inductive load would need a couple of clamping diodes to limit the back EMF spikes.by softfoot - RAMPS Electronics
I have found a number of projects that I would like to print from "thingiverse" but "Repetier Host" complains that some of the STL files are non-manifold and when I try to slice with Slic3r the preview has holes and gaps in it. I have tried repairing with Slic3r and various online services but often without success :-( Other people dont seem to have problems printing these files - so why do soby softfoot - Slic3r
Yes, I checked that ... it is set to "1" ... but surely I only need ONE level because the M32 calls are not nested one within another ... just multiple M32 calls within the top level .GCO file ??? Daveby softfoot - Firmware - Marlin
Further to THIS TOPIC I can now add the following to the "end of job" gcode in Slic3r :- M32 P !/MUSIC.GCO# and it happily plays the music file :-) If, however I put 2 or more in sequence Marlin throws an error "Exceeded subxxx call" and halts without playing anything. According to the documentation the '#' flag is supposed to stop Marlin from going any further until the M32 has finisby softfoot - Firmware - Marlin
Hi, thanks for the reply - a speaker IS fitted, and the file music.gco DOES play with :- M23 /MUSIC.GCO M24 but just not at the end of a print job. After further research I have discovered that the way to play a .GCO file from within a .GCO file is to use the following command :- M32 P !/MUSIC.GCO# and it works very well. Thanks all, Daveby softfoot - Firmware - Marlin
Hi, I need to buy some (4) new 8MM smooth rods of up to 500mm in length. Can someone please suggest somewhere I can buy reasonable quality ones at a reasonable price and shipping (I'm in the UK). Best regards, Daveby softfoot - Mechanics
I want to be able to play a song over the speaker fitted to my MK3 I3 at the end of a print job and repeat it until I come and stop it. With the music on the SDCard I can play it via the serial connection with :- M23 /MUSIC.GCO M24 and I can repeat it by reentering the same commands :-) However, when I add this to the end of job gcode (in SLIC3R's setup) the job completes OK and the controlby softfoot - Firmware - Marlin
How would you do this in the PC ?? I usually print from the SDCard, but I could revert if necessary. Daveby softfoot - Firmware - Marlin
Does Marlin support conditionals (as implemented in Slic3r) ?? I want to be able to pause a print at a specific layer or height to insert a nut or magnet without manually editing the GCODE - the scope for getting it wrong is huge. Also what about "while" loops and "goto" or "branch" ?? Perhaps there are other ways to achieve this ?? Regards, Daveby softfoot - Firmware - Marlin
I am rather deaf so I would like to play a sequence of short tones at the end of a print job and have it continue until I hear the tones. At the moment I have a fairly long sequence of tones encoded and it works a treat but as far as I can see the only way to get a continuous output (without a ridiculously long script) is to specify "p0" which gives a continuous single tone. Unfortunately, theby softfoot - Slic3r
That achieves nothing except re-enabling M106/7. What I need is for E0_AUTO_FAN_PIN to work on PIN 7 with it under GCode control as well. *OR* that the fan to be constantly ON at say 10% when the extruder is not in use and under GCode control when the extruder is in use. I dont mind which. Daveby softfoot - Firmware - Marlin
My printer is a "Geeetech i3 Pro C" with a "GT2560_RevA+" controller board and both the controller fan and the fan that cools the extruder/extruder stepper are wired between 12v and ground and are NOT controllable at all and are permenantly on. PIN7 is connected to the PWM fan that I am using to cool the "part" (work piece). So, how do I control the "part" fan in the way I need ?? Regards, Davby softfoot - Firmware - Marlin
I am running 2.0.5 bugfix and want the part cooling fan to come on when the extruder temp is >50. So, in configuration_adv I have defined the following :- #define FAN_KICKSTART_TIME 500 and #undef FAN_PIN #define FAN_PIN -1 #define E0_AUTO_FAN_PIN 7 #define E1_AUTO_FAN_PIN -1 #define E2_AUTO_FAN_PIN -1 #define E3_AUTO_FAN_PIN -1 #define E4_AUTO_FAN_PIN -1by softfoot - Firmware - Marlin
I have a Prusa I3 Pro fitted with a FYSETC Mini 12864 graphics control board and I find the rotary encode is rather erratic (NB I saw the same issue with the original LCD panel) - can someone please point me to the code that handles and debounces the rotary encoder ?

Many thanks for that!! Strewth, someone obviously spent a lot of time on this issue :-) Getting the x-axis rods exactly parrallel will be a challenge! At the moment my bltouch is mounted behind the nozzle at about 50mm, so any twist will cause a significant error :-( I guess making sure the bed is level wont help very much since the twist is still there?

Hi, I have a Geetech Pruse I3 Pro C (Acrylic) with a BLTouch sensor and a plate glass bed - I know the bed is not level (it is low on the right - x axis). I am using Marlin 2.0.5 and it is configured to use "bilinear" leveling with a 3x3 probing matrix and "extrapolate_beyond_grid" defined. I also have PIDTEMP and PIDTEMPBED defined.

It's a direct drive extruder. I bought a plastic and a metal replacement, the plastic one just dropped in so that is what I am currently using. I would prefer the metal one but it needs a little "bodging" to fit it so I'll do that at some point. I cleaned the nozzle with the "cold atomic" method and then cleaned the thing out with an needle (the ones for sale on eby are actually accupuncture neeby softfoot - Prusa i3 and variants
I'm tearing my hair out over a problem with a replacement MK8 extruder. I had the beast running quite well but then the tacky plastic extruder arm broke. :-( I gather it's a common problem with these printers. So I bought a replacement arm but now the prints are rather "blobby" on the outside and it oozes for a LONG time after a 50mm manual feed (10-15 seconds) and quite a lot of filament.by softfoot - Prusa i3 and variants
