Hey Chip,

Having the same issue... from my measurements I have the 8mm x 1.25mm threaded rod (what came with the kit) which would require 2560. I've adjusted it to the correct number (and even taken it up as high as 4000), and it seems to make no difference, I still have about a 3-4mm gap between the bed and the nozzle.

Am I missing something? Is there another variable I should be adjusting or possible issue afoot?

I have the auto-level version if that makes any difference & the nozzle level was functioning correctly on the stock firmware when I first set it up. It auto homes fine and has the right height of the bed when auto-homed.

Appreciate any thoughts you might have.
boomhaeur: Take a look at the #define Z_PROBE_OFFSET_FROM_EXTRUDER value. It will vary based on how far above your extruder your sensor is mounted. Mine is currently set to -0.7 based on my setup.

I have noticed, though, that the sensor that comes with the 3DP12 does vary by a few tenths of a mm, which is not good. I am wondering if it is due to the fact that the sensor is only powered by a 5V source when the datasheet lists the minimum voltage as 6V. Has anyone tried hooking the sensor up to 12v/24V and using a voltage divider on the output to get it back to 5V? I had a capacitive sensor on my last printer that was powered by 12V and it was much more accurate.

Thanks... have played with the setting (between -5 & +5) and doesn't seem to make any difference.

I'm wondering if I've missed something when trying to enable the auto-levelling in the script. (it's not even going down to the point where the light kicks on for it)

Actually RyanE you were on the right track... I'd missed un-commenting a couple of lines in the auto-leveling section and once I did that your suggestion seems to have started taking effect although now I think I've got a z-axis calibration issue as 1mm seems to move almost a cm on each increment.

Update: I have no idea why but my stock threaded rod/motor combination wanted ~350 as a steps/mm. As soon as I dialed that in, then got the auto-level functions set right things started working just right. SD card was giving me some grief but printing from USB via Pronterface has things coming out beautifully.

First off, thank you Chip. Having compilable firmware for my Hictop 3DP-17 is a life saver.

I am another one with a whacked out Z steps per unit. It's like it's using CM instead of MM. I set it to 400 and uploaded it and it was close. It was dragging through the previous layer now a little bit, but it was way better than being several mm above the bed. Setting the steps for Z to 450 seems to have it dialed in. I would set my zero and using my dial calipers as a depth gauge, I noted the distance between the bed and the top of the extruder stepper. I then sent a G1 Z0.35, measured the new gap and subtracted the difference. I was able to get it to within 0.03mm.

This is great, but it's WAY too illogical!!! It should be around the 2560 value, not a 2,110 step difference! Is there some other parameter/variable that could account for this weird discrepancy?

Hictop 3DP-17 does anyone have a zip file of source with leveling enabled so I can load it up please.
secondly has thermal runaway been solved on pla?
does it print okay without introducing other issues?

just I'm happy compiling- just less sure on other steps.

thank you

As a side note I fixed hictop steps on encoder LCD etc on previous version, but this version doesn't work well for me so far

* edit* got it sorted out, i guess it decided not to compile because it's thursday or something..now if i can just get the nozzle to bed gap issue fixed i'll be good to go.

trying to complile the code in arduino to upload but I keep getting "exit status 1 missing binary operator before token "(" in the conditionals.h tab
right at the

Code: Select all

 #if ENABLED(DOGLCD) 
any ideas how to get it working properly? the firmware is straight from the download file with no mods.

also another issue and the reason i was starting with the fresh code, I had previously flashed the board with CL's version (complied with no issues before) and everything was working well except the nozzle to bed gap would be off a few mm at the start of the print. Manual bed level, it's set to the correct gap when it homes but when it starts the print it doesn't lower the nozzle to the proper gap. Pretty new to printing and so so with code but i'm not sure what i need to adjust in the config. only other solution is setting a z offset in the slicer. I tried printing with Cura, tried it in repetier , same issue.
