Topic: Repetier host
Anyone got the press going with the new repetier host? I have it running etc except but it prints like a quarter inch above the bed.
Re: Repetier host
I've been using it in place of Soliprint with no issues. It performs the Z calibration before each print on it's own. (This is using the Solidoodle version of RH, downloaded from their website.)

Re: Repetier host
Is this the correct download?

Re: Repetier host
Can someone walk me through hooking the Repetier up to the Press?
Re: Repetier host
I don't know why solidoodle is only supporting that really old version. The new version is really really nice.

I found the version of Repeteir on the Solidoodle website that has the Press configurations included.
Re: Repetier host
My issue is that version is a generation behind. Lacks a ton of features and the interface is all different. The new one also supports the far superior Cura engine. Anyone get it working with the current repetier host? Also when I run the other one it doesent do the multipoint z probe stuff. Only does one point.
Re: Repetier host
I'm not sure how some are getting the auto calibration to work before the print job. The nozzle keeps staying about 1/4 inch above the bed each time... is there something I'm missing?
Re: Repetier host
Same with me.
Re: Repetier host
I'm using the SD RH version just fine with no issues. Make sure you select the Press under printer settings.
I have been running the bed at 90C and hot end at 240C

Re: Repetier host
We do not use the newer version of Repetier Host because it has gone closed source, so we are unable to create a custom installer for it. You can of course use any version (or any other software) as long as you have the correct connection settings and set your start code to include G29. In the newer versions of RH, go to the Preview tab, then the G-Code Editor tab and select Start Code from the dropdown.
The reason the new RH is only touching the bed once and printing above the bed is because it is homing Z and not actually probing to measure the bed and not using the Z offset.

Re: Repetier host
What code is used to move the probe up and down?

Re: Repetier host
Code G31 and G32, however, they are not active in the current revision of Press firmware, SolidoodlePress_11262014.zip.
Only gcode G29 can move the probe and is active in the fw.
Re: Repetier host
The movements to lower and raise the probe are included in G29 or when homing Z. I could easily implement separate codes but I'm not sure I see a use for moving the probe unless you're probing or homing, it just creates the need for extra lines of G code.

Re: Repetier host
I think I almost have RH106 working correctly. I switched filaments at the same time and with my first test the amount of material extruded was obviously way off, so I calibrated using http://www.instructables.com/id/How-to- … /?ALLSTEPS and it measures pretty close to 100mm for 100 extrusion, the setting I ended up with was 98.7 steps, using the default material it was set to 138. I've printed a couple test 10x10x10 cubes and it seems like perhaps the extruder is a little too low? It seems like it's sort of "smearing" the material around. Is that what would cause what I'm seeing, or is there a different cause I should look at, and if that indeed is the problem how do I adjust it in RH106? Temps are at 250/90.
Re: Repetier host
Those calibration measurements are very similar to what I got, using RH .85. I usually just see the smearing on the first couple layers though. When things started to get too stringing or smeary, I also tried lowering the temperature by 5 or 10 degrees, which helped some.
I also followed a procedure to calibrate the extrusion multiplier (for Slic3r) to .8. (the solidoodle default was .7)
Despite calibrating to 100, I've set my extrusion steps slightly higher at 105, because it seemed like things were being starved for material, especially when doing solid layers on top of infill. That still seems to be the case, so I'm not sure what to try next. Perhaps slower print speeds. RH seems to run a bit faster than SoliPrint.

Re: Repetier host
hm. Checking the options for Slic3r in RH106, the extrusion multiplier (filament settings tab) is 0.6. I see it's 0.7 in soliprint.
The reason I was wondering if perhaps the extruder was a little too close to the piece is that I could see the cube sort of squishing around a bit as the head moved. Maybe too high of a bed temperature, not letting the piece cool enough as it's being printed? Those two cubes weren't at the same temp, one was at the 250/90 I specified, the second was at 240/90 but perhaps that was still too high.
Re: Repetier host
I've got the latest version of Repetier Host running (Mac) and trying to print this empty cube for some calibration: cisana.net/extruder-calibration (Sorry, I'm apparently allowed a maximum of zero links so you'll have to copy/paste.)
The brim and base all print fine with Repetier and their suggested settings but when it gets to the walls of the cube the speed picks up and the extruder can't seem to keep up. The filament isn't coming out fast enough leaving gaps and I hear (and see) the thumping sound of the extruder wheel stuttering. I then printed the same cube, with the same settings (as many as Soliprint's Sli3r gives you) on Soliprint and while it printed the walls a lot more slowly, it went fine without any stuttering / thumping.
Any idea what the difference is with Repetier's settings and Soliprints that would cause this?
Re: Repetier host
Are you using the filament that came with the printer? So far after switching to the roll I bought (Shaxon is the brand) I haven't had any more stuttering/thumping from the extruder.
I bet you and I are seeing the same thing in terms of settings. I've tried the same between soliprint and RH106, same results as you, soliprint looks ok, RH produces what I posted above.
Re: Repetier host
When you print 10x10x10 cubes are you printing one at a time? printing very small items can be a problem as the layers do not cool at all before the next layer is put down. You may want to try printing multiples (use copy command) or just try a 20x20x10 or even 30x30 x10 cube.

I am, but I have a new spool from Push Plastic coming later this week. Have you experimented with any of the speed settings in Repetier/Slic3r? I looked at those but since I don't know what they are set to in Soliprint, outside of travel speed, I'm not sure where to start.
Re: Repetier host
What I did is move through the software choices. First Soliprint, then Repetier-Host Solidoodle and now I am using Repetier-Host v1.0.6. I simply used the "Press" preset in RHS. I didn't change speeds. Mostly I tweaked infill %, extrusion multiplier and Z-offset (the main one) until I had good prints. I saved these settings. When I moved to RH, they were all available there, I assume because I did a default install for directories.
As far as your issue, you could try slowing down the print I suppose, but likely just doing 1 copy at the same time will at least tell if lack of cooling is the issue. You may want to manually move them pretty far away from each other and get them closer to the edges to add to the cooling time. Although this may also have an impact on the sticking as the temperature of the plate may not be uniform. I found covering in Kapton and increasing to 100 degrees helps. Now I need to pry parts off.
Re: Repetier host
I went through all the Config->Printer Settings tabs and set them to the same as what's in soliprint, then did the same with the Slic3r config. I just tried printing four cubes instead of one and that definitely helped, the corners look much better. I think I need to bump up the amount of material extruded a bit, going to try that now. Last thing I'm seeing is that all four cubes measure very close to 10.05 (+/-.03) in one dimension but they're all around 9.70 (+/- .03) in the other. I assume I need to tweak the Steps per mm setting for the axis that's off in the EEPROM settings, but I need to do another print first because I wasn't paying attention to the orientation when I pulled them off, whoops. 
Re: Repetier host
If the smaller width is on the Y axis, you might want to check the tightness of the set-screws on the gears that connect the stepper to the shaft at the rear of the printer. I had an issue with those, but my prints were off by much more... resulting in rectangles rather than cubes.
