Z home position issue
Hi, I'm working on my first printer and bumped into a Z home positioning problem. The X and Y directions ar OK. They move as I excepted and return to the home position when I press the appropriate...
View ArticleRe: Z home position issue
Sounds like the Z is trying to go too fast and failing to step properly. Look for: #define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0} // set the homing speeds (mm/min) Try reducing the 3rd term (4*60 in...

Hello all, I'm building a 3d printer using the Marlin firmware on a RAMPS 1.4 board. I'm having an issue with my endstops not being triggered in repetier-host. I've sent the M119 code to check the...

US price probably does not include vat because they dont have that. EU price probably includes it, most probably all components have that included in purchase price. So the eu price is comparable if...

I emailed Arthur Wolf and he informed me that the breadboard route has issues. He also let me know that the production Smoothieboard could theoretically run 8 or 9 steppers total and that it's in the...

Thanks for the info (again!) - I'll try to check this out to confirm. I got the new steppers today (ie the correct ones), one of them having a nice severed wire as an added bonus! They're wired in but...

Edit: I figured out the issue. I disabled some features I wasn't using such as LCD feature controller and the ticking is gone. I bought a ramps-fd from geetech. (I couldn't find any in the US). I'll...

That's kinda what I heard. There have been a few attempts before to port Smoothieware to other platforms but they seem to fizzle out. Smoothieware is getting pretty big and rapidly changing, making...

I think I finally have some useful progress at last! New PSU and it seems to be behaving far better, and have moved the carriage & bed to their end stops before switching on. They behave quite...

I'm trying to make sense of the v1 rev A board from geetech. I looked at the relevant schematics and I can't seem to find "P404" as labelled on the geetech board. Is this a power in? What does it...

If your bed reads below the minimum temp, it won't heat. Same goes for the hot end (for hot end readings). This is because a very "low" reading is also the same as having the thermistor disconnected....

Hi I'm also working on my first printer and have problems with endstops. So don't be 100% sure that my advice is correct, but might help until you get the final solution from an expert. I use Marlin...

P404 is the heat bed output, labelled D8 (and also Digital pin 8 in Arduino terminology). To support the inverted heaters requires a patch to the Repetier code which you can find on my repetier branch...

If you want to make exports as individual you would be at disadvantage idd. But, you could make a small company for that purpose and that means when you export goods, you get back the vat you paid,...

Thanks Bob! I applied the patch found here [github.com] to the latest repetier firmware. The ui.cpp section to patch does not exist anymore. Regardless the patch works. Thanks. BTW I saw older...

Yes, I am very interested. They seem to offer great performance for the price. I am a hardware guy with very limited software skills so I cheer you on instead :)
