You can home to Y max which would be over there in a standard setup.January 23, 2019 at 7:04 pm #85224
I’m drawing a blank on how to set it up. Do I need to update the firmware or can I just issue the command and save it?January 23, 2019 at 7:31 pm #85239
Config.h line 920 Ymax
/ Direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1
Make sure to also set an accurate bedsize.

Do I need a max end stop?January 23, 2019 at 8:50 pm #85256January 23, 2019 at 8:55 pm #85258
Maybe I’m doing something wrong but if I home X and Y, if there was a part sitting on the bed it seems like it would hit the extruder or X axis since the bed moves to the back.January 23, 2019 at 8:56 pm #85259
I guess the alternative would be to finish the part and then Y home max?January 23, 2019 at 9:01 pm #85261
Well, you shouldn’t home with parts on it 🙂
When you’re print is done, the gantry is higher than the part, so it is fine to move the bed, but you might just scratch the top.
I bet what you’re really interested in is tweaking the final gcode to move the part out so you can pop it off. I am AFK, but mine goes something like this:
Retract a tad.
Slowly move -20x and -20y to cleave off that last touch spot.
Move Y to +200, which pushes the part out for me to grab it.January 31, 2019 at 8:47 am #86705February 1, 2019 at 10:46 am #86877
I would be pretty happy with those prints. Not sure why you would have to re-level every time though.February 1, 2019 at 12:19 pm #86890
I remounted the Mk8 extruder. It has some play in it. Hopefully this time I have it attached more securely.February 1, 2019 at 12:31 pm #86891
I had a couple of problems that I thought were related to the mount. I’m using a different extruder, but the motor would get hot enough to deform the strap, and the filament was pulling enough to cause the hotend to lift a little. I designed a new mount… Where did I put that… I should probably just post it to TV.February 1, 2019 at 12:40 pm #86892February 1, 2019 at 12:44 pm #86896

Which extruder and where is that mount? 🙂 TV as in television?February 1, 2019 at 12:46 pm #86897

These turned out good. I can’t complain with these prints! I just need to be able to “set it and forget it” when it comes to starting a new print.February 1, 2019 at 12:47 pm #86899
TV as in thingiverse.
I bought a aliexpress E3D V6. It’s the right price. but it’s not the standard size, and I ended up replacing enough parts on it that I probably could have bought the genuine one. I think my mount, with the MK8, and not using a BL touch could be a good choice. I don’t hate the MK8, I just wanted the 3:1 reduction for doing finer resolution printing, but I haven’t actually even tried it. :).February 1, 2019 at 12:51 pm #86900
Also, be careful following in my footsteps. I look at this printer a bit as a research printer, and not everything I try works out, or is worth the time it took to get it right. You’ve been warned.February 1, 2019 at 12:58 pm #86903
You’ve been warned.
Ha! I want to use the BL touch. I have the bed leveling sensor on my Printrbot and it works well. I’d like to add it to my ESV2 printer and my new Hevo that I’m putting together. Will the BL touch work with the rambo?February 1, 2019 at 1:12 pm #86905
Will the BL touch work with the rambo?
Yeah, no problems there. It attaches to the ZMin pin, and it needs a servo pin to drive it.
I like it a lot. I bought a aliexpress one first, and it might have been part of my trouble. After I had been using it for a while, I ran the M48 test and it was awful. I’m not sure if I bent the pin or what. Since that, I bought the official BLTouch (which I didn’t like to pay for) and it’s M48 is like 0.0002mm. It’s working fine.
My E3D V6 hangs down much farther than the motor, so I lose a few cm in Z. The BL touch on my mount is to mount it low to reach. If you want to use the BLTouch with the MK8. or titan aero, you’ll have to find or make a better mount.
This is how I mounted the BL Touch to my wanhao duplicator i3, which has a mk10 extruder:

I don’t recognize those settings. In slic3r, there is a setting for how many layers to have the fan off for. It’s in the filament section, IIRC.February 11, 2019 at 2:41 pm #88738

This is using Simplify3D. It works fine with my Printrbot.February 11, 2019 at 2:42 pm #88740
Are you sure you have it wired correctly? Can you control the part fan with M106 S255 or M107?
And just to be sure, your extruder fan is on all the time, or at least on whenever the extruder is hot?February 11, 2019 at 4:42 pm #88765
Yes M106 and M107 turn the fan off and on. I think the extruder fan turns on when it starts to heat up. I don’t get it. I calibrate this thing almost every time I print something.
I see now that I’m sitting in front of the printer it’s laying down good layers. How can it be so off every time I try to print?

It’s not magic. The slicer needs to call M106 after the the first layer. The firmware is just listening to commands. You should be able to look at the gcode and see where it’s putting the M106. I don’t see how this could be a provlem with the printer.February 11, 2019 at 7:07 pm #88787
There is one place I need to check in S3D tomorrow. There is a script when a new print starts where I may have it set to come on automatically.February 12, 2019 at 8:22 am #88836
I found that little pesky M106 command in my start up script for gcode. Thanks for helping with my memory!!February 14, 2019 at 11:10 am #89158February 14, 2019 at 6:01 pm #89194
I’ve printed one of the mounts that holds the camera off the corner of the bed, so it moves with the bed. The puts your focus point always at the same spot on your piece while printing. Haven’t yet put it in place though, need to find a round tuit somewhere first…February 14, 2019 at 9:42 pm #89218
Have you tried the octolapse plugin? It will move the bed to a specific spot to take each photo. The timelapses are pretty cool.
