Marlin Firmware Upgrade 1.1.0 RC8 & RCBugFix (For R1 & R1+PLUS)

Understood. I used your version. I'm getting tons and tons of skipping though, as if the printer is overloaded and it's struggling to process things. I've tried it on my powerful rig too and still get the same result. I'll try it with a new USB cable since the one I have is questionable.

 

Wasn't the USB cable anyway! Still getting that skipping. I'll record it later and put it on Youtube. I've got to head out now though.

The z-axis homes before each print, so I'm going to have to get the IR sensor working as the heated nozzle damages the PRINTinZ plate on contact. The leadscrews do appear to be turning as the x and y axis move though, which is great.

 

I must really. Be doing something wrong. I level it. Save it. Issue an M501. Only have G28 in my start script. Yet my bed still is way off. It becomes a guessing game with a G29 S4 Zxxx command. And when I somewhat find something that lays down some decent lines, half the time it's digging into the bed on one side and not on the other. Like it's not compensating for the mesh levels. Usually the only time I can get a print to survive is by adding a raft just so it has something to stick to. I'm in RC7fix with Marlin .11

 

thank you @WheresWaldo. definitely will add the G29 back, but based off your response, knowing myself, the filament removal so 98% chance the issue.

 

Hi guys! I've had the chance to do a little more testing. Reuploading the firmware with new settings does not wipe the MESH point values, so I'm going to try plugging in the IR sensor again now that I have done the MESH leveling with the Leadscrew endstops.

 

Well I didn't know that.

Changing the firmware to re-enable the IR sensor makes everything work. The only different is the z-offset is much lower now since you have to account for the fact the printer things the trigger point is '0'. Your z-offset is whatever the height difference between the nozzle and the sensor is.

It'll be very troublesome whenever I want to redo mesh leveling but I can't see a way around having to switch the IR sensor for the z-endstops each time just yet. I'll keep thinking.

EDIT:

Nevermind about the 'z-offset' part above. Apparently the printer still won't go below the trigger point of the IR sensor. Just going to have another play around with the firmware and see if I can get it to ignore the sensors input after homing like Waldo mentioned before.

 

Your logic seems solid on paper. No need to probe in the middle since the map of the bed is stored in MESH and you are just wanting to find out at what point you want to place that overlay. I think you are onto something there.

 

Hi guys. Here's a step by step guide on how I got MESH working with Jimbots IR sensor. It wasn't too difficult in the end. Just download the latest build of the firmware for your configuration of machine that WheresWaldo has linked above and follow the steps below.

1) Level the x-axis. I used this to level it against the bed: http://www.thingiverse.com/thing:280974

2) Use Dial Indicator to level the bed. Take readings and shim the sides you need to until the bed is as level as possible. I used this bracket to attach it to the printer: http://www.thingiverse.com/thing:571047 but this one might work out better: http://www.thingiverse.com/thing:185643

3) Change the following in the firmware:
#define Z_MIN_ENDSTOP_INVERTING false //--ROBO-BH set to true to invert the logic of the endstop.

#define Y_PROBE_OFFSET_FROM_EXTRUDER 30 //--ROBO-BH Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER 3 // Z offset: -below +above [the nozzle]

#define min_software_endstops false // --ROBO-O If true, axis won't move to coordinates less than HOME_POS.

#define Z_MIN_POS -5 // --ROBO-O Allows the nozzle to go up to 5mm below the IR sensors trigger point.

4) Send the following command to your printer:
M502

Not really sure if this is necessary but it can't hurt. I only did it because I wasn't sure whether there would be any 'cached' data that would screw me up. M502 reverts to default settings (i.e. the firmware you just loaded).

4) Next perform MESH leveling.

You can either measure points using paper and your nozzle the same as normal, OR you can take points using your IR sensor.
It doesn't matter, this will only affect your z-offset. The IR sensor is probably more accurate.

Send G29 S1 to move the extruder to the first point.

Lower the carriage the IR sensor triggers or the paper gets hard to move under the nozzle.

G29 S2 will store the point and travel to the next point. Keep doing this until last point has been probed.

5) Send M500 when the sequence is complete to save the points.

6) Now you need to figure out your z-offset.

Run a test print and send the following commands. Cancel and repeat until your nozzle is the right distance away from the
bed.

M851 Z-x.xx (generally the distance above the bed your IR sensor triggers, but mess with it)
M851 (to check that the offset value was accepted)
M500

And that's it! Truth be told, I performed MESH leveling twice out of interest and ended up with different values and a different z-offset both times. This is characteristically inconsistent of the Robo3D but hopefully it'll be okay going forwards. Good luck!

 

I'll have to try the newer version of ABL because that is what I did but I couldn't get the nozzle to print lower on the initial rc7 release. Maybe they fixed something. I knew it shouldn't be that hard and didn't have the time to keep digging. If it works for mesh it should work for ABL.

 

Yeah I had tons of trouble getting the nozzle to go lower than the trigger point of the sensor. I ended up having to use M851 in the console for the z-offset. It will ignore Simplify3D or setting the offset in the starting code unless it's using M851.

 

@WheresWaldo Any ideas why I can't compile? Robo3D's "ROBO3DR1V3_06112015" compiles fine but I can't get any from the 9-30 or 9-18 to compile.
