Folgertech Prusa i3 Marlin firmware -see attached config.h When I hookup printer i am able to move axis and have them setup so moving correctly. Endstops: X / Y - optical Z - mechanical Y axis - Back right x axis - right side z axis - right side All hooked up to min on ramps (had guy setup for me and left configured that way) Issue: I home all axis, even if just move axis to and endstop it becomes 'triggerred' like it's supposed to. However I'm unable to move any of the axis off the endstop once it has been triggered. Any help would be greatly appreciated.

The power comes into the ramps 12v 5amp circuit. This goes threw the 5amp fuse threw D1 and into the vin pin on the mega

The mega can take power 3 ways. the dc jack and the vin line are the same, they go to the voltage regulator which turns 12v into 5v.
The 3rd way its to take 5v from the usb cable..

If the regulator is broken it still work with usb applied. (ie what you have)]]> Dust Prusa i3 and variants Wed, 17 Jan 2018 00:11:37 -0500 https://reprap.org/forum/read.php?406,805172,805879#msg-805879 https://reprap.org/forum/read.php?406,805172,805879#msg-805879
Busy with work so not alot time work on it right now. Think time to take apart and go through step by step again.

Have spare ramps and mega. I'll redo everything hopefully in next week.]]> Booda Prusa i3 and variants Tue, 16 Jan 2018 18:43:09 -0500 https://reprap.org/forum/read.php?406,805172,805759#msg-805759 https://reprap.org/forum/read.php?406,805172,805759#msg-805759 Dust Prusa i3 and variants Mon, 15 Jan 2018 18:24:27 -0500 https://reprap.org/forum/read.php?406,805172,805713#msg-805713 https://reprap.org/forum/read.php?406,805172,805713#msg-805713
Now - No longer have 12v power. Lcd will come one once I have 5v from usb though. I am able to move axis, but when endstop on z axis is hit lcd went blank again.

Possibly bad endstop, would it have fried ramps board if no 12v power?

ugh. This printer been nightmare since bought it but determined to get working (again).]]> Booda Prusa i3 and variants Mon, 15 Jan 2018 11:21:22 -0500 https://reprap.org/forum/read.php?406,805172,805422#msg-805422 https://reprap.org/forum/read.php?406,805172,805422#msg-805422

Is it ok run all 3 axis on min or should 1 be on max?

Will try it out this afternoon when can get time work on it.]]> Booda Prusa i3 and variants Fri, 12 Jan 2018 13:53:48 -0500 https://reprap.org/forum/read.php?406,805172,805177#msg-805177 https://reprap.org/forum/read.php?406,805172,805177#msg-805177 o_lampe Prusa i3 and variants Fri, 12 Jan 2018 11:39:02 -0500 https://reprap.org/forum/read.php?406,805172,805172#msg-805172 https://reprap.org/forum/read.php?406,805172,805172#msg-805172 Marlin firmware -see attached config.h

When I hookup printer i am able to move axis and have them setup so moving correctly.
Endstops:

X / Y - optical
Z - mechanical

Y axis - Back right
x axis - right side
z axis - right side

All hooked up to min on ramps (had guy setup for me and left configured that way)

Issue:

I home all axis, even if just move axis to and endstop it becomes 'triggerred' like it's supposed to. However I'm unable to move any of the axis off the endstop once it has been triggered.

Any help would be greatly appreciated.
Thanks.]]> Booda Prusa i3 and variants Fri, 12 Jan 2018 11:24:48 -0500
