If you increase the "flow rate" you increase the amount of filament extruded, decrease then decrease the filament.by kd6hq - RepRap Host
I'm using Repetier-Host V2.0.5 I'm trying to set up the extrusion length setting on extruders 2 and 3. When I do I get the following message: echo: M92 Invalid Extruder 2 echo: Settings Stored (405 bytes) Instead it stores the values to Extruder 1. One of the things I don't understand is that if extruder # 2 is invalid, then why store it to # 1? Anyway this is on Diamond 3 color head setup. Anby kd6hq - Repetier
It looks like to me the latest stable version of Marlin is 1.1.2 ?. I see mentioned, bugfix-1.1.X and 1.2 which as I understand it changes the file structure as well as starting support for 32 bit CPU's. With the advent of 32 bit processing will the firmware be backwards compatible with 8 bit processors? thanksby kd6hq - Firmware - Marlin

When I compile I am getting the following error: "The given LEFT_PROBE_BED_POSITION can't be reached by the Z probe." I'm not sure what this error message is telling me. #define X_MIN_POS 0 #define Y_MIN_POS 0 #define Z_MIN_POS 0 #define X_MAX_POS 150 #define Y_MAX_POS 225 #define Z_MAX_POS 250 // Z Probe to nozzle (X,Y) offset, relative to (0, 0). // X and Y offsets must be integers.by kd6hq - Firmware - Marlin
Not any luck so far finding a vendor that has all 3 colors. What I have found tends to be ABS not PLA and the diameter is usually 3.0 not 1.75. The Indian Summer colors sound interesting, I will take a look at it. Dealing with a clogged hot end so search will have to wait.by kd6hq - Firmware - Marlin
No so far I have not found anyone who has all 3 colors. I have not finished looking yet and will report back if I do. I saw a picture of a prototype Diamond hotend with 5 filaments. It looked like they just drilled 2 more holes in the existing head. Should be interesting. I've also read about some experimental mixing using 6 colors It's not in production yet but at least someone iby kd6hq - Firmware - Marlin

o lampe What is RRF mixing? I thought I could search on internet for it but I have not been able to.by kd6hq - Firmware - Marlin
I'm not sure that is the correct way to define the colors, but it seems like it may work after I fix a couple mechanical problems (stepper slipping). I ended up placing the definitions is the slicer startcode. ; Yellow M163 S0 P0.5 M163 S1 P0.5 M163 S2 P0.0 M164 S3 P1 The P1 stores the setting under S3 in the eeprom. Since I did not store them in the eeprom, I left the P1 off or you can sayby kd6hq - Firmware - Marlin
Well I've printed my first test piece and it did not turn out too bad. It is a simple 3 layer part with red, green and blue. 20 x 20mm sq and 2 mm thick. Each layer is a solid color without any mixing. The second try called for the same size part but with "mixing". The colors picked for the second part are yellow, cyan and saddle brown. Yellow = 50% red, 50% green and 0% blue or R=255, G=25by kd6hq - Firmware - Marlin
I will try that. It will take me a couple of days (waiting on filament) but I will report back what I find. Perhaps someone will add more information while I'm waiting. In the mean time did you see this? It is a true mixing hot end, it has a motor and a mixing chamber to actually mix the material.by kd6hq - Firmware - Marlin
How does weight correspond to a color. How do you calculate the P value for a color. Using R, G, B how do you calculate P where Saddle Brown uses R = 139, G = 69 and B = 19 So what would the definition look like? M163 S0 P ?? M163 S1 P ?? M163 S2 P ?? thanksby kd6hq - Firmware - Marlin
Interesting discussion. the digital dentist: Thanks for mentioning EAA.org, what an opportunity for and entry in to Solidworks. n9jcv Sounds like we are about in the same position.

Thanks I am using dual stepper motors on the Z axis. The movement is no where near what it should be. Not only is it very slow movement it also does not move the proper amount. If I change to Marlin firmware the motors work as expected, but reload Repetier firmware and it's back to the slow movement. As far as I can tell the settings are the same in both firmware, so it must be something thaby kd6hq - CoreXY Machines

o lampe My mistake for some reason I thought you had also had a Repetier version. I did build a CoreXY, that is what I am working with right now. The printer is not quite done yet but should be ready to test by early next week. I have ordered the Aluminum to make the bed and it should be here soon.

o lampe How is your project coming? I seem to be stuck and not making any progress. Would you mind sharing your files for the Repetier firmware for the RUMBA board? I would like to compare your with mine to help try and figure out that I am missing.by kd6hq - Firmware - Marlin
That's why you go thru the calibration process. The calculations that you are doing are just a starting point. There are several things that can make the calculated value be incorrect. One of them is pressure that the spring exits on the filament, another would be the actual diameter of the gear that the filament passes over verses the designed diameter. So even though your calculations maby kd6hq - Firmware - Marlin
I know what you mean, I read lots of post on this forum using a translator.by kd6hq - Firmware - Marlin
For what it's worth: Or you could just calibrate the Z direction. As far as I know on the RAMPS boards micro steps 1/32 or 1/16 depends on which stepper driver you are using. If using the DRV 8825 drivers it's 1/32, A4988 = 1/16. But is you go thru the calculation procedure it won't matter which ones you have.by kd6hq - Firmware - Marlin
thanks o lampe WOW how did I miss that! Maybe I need to take some reading lessons. Makes me wonder what else I've missed..... // This defines the number of extruders // :[1, 2, 3, 4] #define EXTRUDERS 1 // // Enable if your E steppers or extruder gear ratios are not identical #define DISTINCT_E_FACTORS // I guess it's time to really sit down and go over this line by line......by kd6hq - Firmware - Marlin
Observation: Well I'm still investigating the calibration of the 3 stepper motors when using a Diamond hot end. It that Marlin 1.1.0-RC8 (& Bug Fix) allows for the calibration settings of 3 or more extruders I have been looking for a way to calibrate each of the stepper motors. The simplest way I have found so far is to simply define 3 extruders and the associated thermistor settings etcby kd6hq - Firmware - Marlin
I checked by doing a recompile and I did not see any warning messages like that. I don't know enough about programming to know the why's and why not. I went with Rumba instead of the Duet for the same reason. I could not believe that a new board with a 32 bit processor was designed with only 2 extruders on board. Especially with the growing popularity of multi colors. They probably would hby kd6hq - Firmware - Marlin
I did a quick search on e-bay the unit is the same cost but the shipping is a lot cheaper to California any way. I've never added one to a RAMPS board so I don't know how many you can add. The web page (reprap.me) show one unit that can add 3 at once so I suspect that 's all the RAMPS 1.4 board has room for. You may need to modify your "pins_RAMPS.h" file. To add the additional pins for theby kd6hq - RAMPS Electronics
o lampe The Vref may be a little low, the steppers are rated at 1.5A per phase. The setting of .5V should give about 1 amp per phase so that's 2/3 of the full capacity so I think that will work. It did not occur to me until now I suppose the stepper drivers could be mixed and use DRV8825's for XY and A4988's for Z. Prior to the compile I do get some warnings, in both RC-8 and RC-8 Bug Fixby kd6hq - Firmware - Marlin
dc42 - thanks for the link I have not really thought about it but it does make since. What would make more since would be to just the retract the one's you were using. The firmware is not far enough along to be able to do that, yet. So retracting all 3 is probably the best way.
