This is a homing problem but I have no idea what to do. I need to edit something.
Try plugging x and Y steppers in the other way.
Indeed! In redeem all end stops are software configured. You can set it using either g-code m574 or directly in the config. An M574 without parameters should give you the current config.
Z stop works. X and Y however…
Recv: ok X1 stops: x_neg , X2 stops: , Y1 stops: y_neg , Y2 stops: , Z1 stops: z_neg , Z2 stops:
Did you see this vid? http://www.thing-printer.com/end-stop-configuration-for-redeem/
Yes. And honestly I still haven’t wrapped my puny brain around this concept. I will re-view the video and figure it out! Thanks.
I am still having problems. The printer is working great except for this homing problem.
Well, that is a problem worth fixing:)
Do you have end stops by the end where the steppers are moving, or are they located on the opposite side? If you need to change direction for homing, you can use negative values for the travel_x and travel_y values.
I agree! I do not have physical end stops at the “far” ends, the Y stop is on the left end of the axis and the Y stop is at the aft end. I could put stops on but I assume that virtual or soft stops can be configured. I just can’t figure out how.
Ok, so when you press the end stop at the far right (in the video), I assume it says “X1 end stop hit!” In the OctoPrint terminal window. If so, you need to write “M574 X1 x_pos” to change the direction in which is stops the stepper.
This looks like the default config file and it should be the same for everyone. Do you get any writing in the console when you press the end stops?
My current default.cfg
Default.cfg should not be altered, it will be overwritten by any subsequent software upgrades. Please place your changes into local.cfg.
There is no stop on the right side, the x stop is on the left near the X stepper. It does say “X1 end stop hit” when I trigger the stop.
As to local.cfg, I should copy the entries from default I want to change and then save them as they will load in subsequent redeem starts. Correct?
So to stop the X axis at pos X 190 (right hand side in video)I need a soft stop at that position? How do I do that?
And thanks for helping me, somehow I am having trouble with this.

If the end stop is on the left side, but your objects are printed right (not inverted) then you need to define travel_x = -0.18 in the [Geometry] section
Ok, I have re-init’d the BBB to start from scratch. The printer still had the hoing problem but is printing pretty well. I have edited the local.cfg and will restart redeem after this print is done.
[Geometry]
travel_x = -0.18
[Steppers]
direction_e = -1
[Endstops]
invert_X1 = True
invert_Y1 = False
invert_Z1 = True
homing not “hoing”!
Another question, your calibration cube prints well but the size is .2-.5 mm too big. Should I adjust the steps?
When I edit the local.cfg in redeem and try to save nothing happens. It just sits there. When I try to download the file I get “500: Internal Server Error”.
I have edited the local.cfg file in the /etc/redeem folder (see above)
But it is printing GREAT! The Replicape is a much better device than the SAV board!
