Yes, that's the correct part - it's become something of a standard for 3D printing, as far as I've seen.goopyplastic wrote:is the LJ12A3-4-Z/BX what is included in the mg beta kit? Anyone have a list of beta kit contents for those who are rolling their own?
Thanks!

Re: Printing NEW M2 Parts in Simplify 3d Wont Work
Glad you got that figured out. Most likely what happened is you tried to save the file from the main Github view - while the link may say "*.stl", it actually opens up another webpage with the .stl preview; to properly download the model itself, you need to click Raw from that preview page.

Re: Pt100 upgrade problems
The easiest way to implement the 40mm fans in newer Marlin is to use the "auto fan" options in Configuration_adv.h - setting Extruder 0 to pin 6 ("#define EXTRUDER_0_AUTO_FAN_PIN 6") will tell the firmware that, when the hotend is above 50°C ("#define EXTRUDER_AUTO_FAN_TEMPERATURE 50") to turn on th...

Re: M2 Auto-Leveling Kit (Beta)
Ah, so it looks like, basically, a time of flight sensor built from discrete components. I didn't see - does he have any information on accuracy/precision? Also, any experimentation/testing on different bed surfaces - ie, opaque vs translucent vs transparent, reflective vs matte, etc.? The firmware ...

Re: Request for Marlin/Arduino Expertise
Good call on the floating point operation - it adds ~10µS to the execution time of the ISR. I think I've settled on 175 as the reset value - in a newer version of Marlin, it keeps the extra gap between step sets to below 20µS.

Re: LCD case/position change
The side mount ("current.jpg") is likely going away one way or another; either way, it's never been actually secured, it's just that that is as far as the wires run. The front mount option could be made to not interfere with the SD card, but it has a full size SD reader on it anyway (and the adapter...

LCD case/position change
Good afternoon folks. We are working on the case design for a different LCD controller (see photo). The case design that we've been using has the LCD as a standalone item on the side of the printer (pictured in "current.jpg"). Another option is to mount it to the front of the electronics case/frame ...

Re: Request for Marlin/Arduino Expertise
jsc: testing on your modification continues. https://github.com/MarlinFirmware/MarlinDev/issues/35 has some updates, but the short version is that, so far, it works X) I've tested both TCNT1 = 0 and TCNT1 = (0.75*OCR1A) and both work well. That post has some information on the timing. For Issue 2, w...

Re: M2 Auto-Leveling Kit (Beta)
PcS - what optical solution from ultimachine are you talking about? https://ultimachine.com/content/optical-endstop-assembled ? innkeeper - I do agree that it's better to sense the top surface of the build platform, rather than an inductive surface somewhere below it; the inductive sensor, however, ...

Re: Request for Marlin/Arduino Expertise
jsc: The compiler flag was an easy test, so I ran it first. I did add your line of code ("if (TCNT1 >= OCR1A) TCNT1 = 0;") to the end of the ISR (line 761 in my testing version of Marlin) and it seems to have worked - I'm looking for gaps over 4mS, up to 60mS (can't go much lower as that's the gap t...
