First of all thanks to Ryan and everybody else making this seem possible
I am almost there, it has been a challenging journey, hours of googling and assembly…
I went for the dual endstop, i hope it is worth the extra hassle…
Electronics and programming is always a challenge for me, i need full guidance
Hardware:
SKR 1.4 Turbo with 2209 drivers and TFT 35
NEMA 17 from stepperonline, bipolar 1.8°
12V PC PSU
Neje 30W (4W) laser module
Makita knock off China router
Firmware choosen was Marlin_V1CNC_SkrPro_DualLR_2209_2.0.7.2_510-src, have no idea if this board is different from the turbo?
For the TFT i think i used this BIGTREE_TFT35_V3.0_E3.26.x.bin will check…
I 3D printed my own box, very bad design, it is horrible to wire the board in the box.
Working area is 3000x1300x200mm. I reused some old tables, it is kind of a proto to learn what i need to do with vac table and so on. I used some alu 30x30x2mm angle profile for rails, it is to flimsy since i have it sticking out 400mm, maybe with some support it is ok.
So issues encountered and word of advise:
Searching for answers is an horrible task since there are many versions of everything, sometimes the answere can be found in a 3D printing forum, take a moment to think if other platforms could be worth seeking knowledge in, or maybe just ask here in the forum…
SD card: some of my SD cards dos not work for firmware upgrade. I you are having troubles try another one, FAT32 formatted and smaller cards usually better.
TFT reads “No printer attached” be patient you need to wait quite a while sometimes before it disappears.
Laser TTL, you think it is all good you have 12V TTL so you are fit to just put in on F0. Dos not work, the modulation is done on the gnd, so there is always 12V on the signal pin. Cant help you yet, need to find out how to fix that…
I am missing Z1 endstop ( see picture), so i am unsure is it because of i have skr pro firmware (and not Turbo) or is this just the way it is? and what to do about it? where do i wire Z1, an can i keep the Zprobe?
Stepper wiring or steps/mm? I have done no adjusting what so ever, used all recomended GT fittings, when i make x move 10mm it moves 47mm, so did i wire the stepper wrong or i just need to change steps pr mm like when you calibrate a 3D printer?
Again, thank you for making this possible, you are legends in my world
Best regards
