Thermister Tables in Marlin - 10 years ago
I need to enter a new thermistor table in Marlin for my 500C capable pico nozzle, but I can't find thermistortable.h in the drop down menu. I can see it in the folder but when I open it, the whole config opens and I can't locate it. Any help or links appreciated.by cfeniak - General
Change default homing order in Marlin? - 11 years ago
In Marlin, is there a way to switch the auto-home order to home y then x? Default is x then y. I'd like to format the sub routine directly so that I can't accidently call it in the x/y order. Reason: I have built a custom H-bot using all v-slot and no linear rods. I have set up the endstop switches in a fixed position so that the wires to them are stationary. If the dynamic frame is in the oby cfeniak - Reprappers

You will have no problem getting 6mm GT2 belt inside the extrusion if you position it right. You could even get 8mm if you wanted.by cfeniak - Reprappers

Re: Help on choosing the right hot end - j-head vs. magma - 11 years ago
My vote: start of with an "official" j-head. You should be able to find it in a variety of sizes. I've found 0/5/0.4/0.35/0.3/0.2mm. To start off with generic printing go for a 0.5mm or 0.4mm If your focus will be small/detailed stuff then start with a 0.4mm or 0.35mm and then consider smaller once things are good and you've burnt through some plastic.by cfeniak - General
Re: I "slightly" modified my cofee table 
- 11 years ago
QuoteTraveltrousers Looks awesome... My only criticism is that the nuts are visible and are slightly ugly compared to the gears, flip them around (or cover them) and it will look perfect! Great job.... where are the files....?? :p Disagree, looks good. Adds subtle visual variety with out being distracting.by cfeniak - Look what I made!

Nice, I second the Q on source files! I'd love to try this on a bit of a smaller scale.by cfeniak - Look what I made!
Re: Use an Opto stop to pause print when filament runs out? - 11 years ago
bkpsu I haven't tried it yet but if you implement M43 above it homes only the XY. Hopefully when you "resume print" it works out.by cfeniak - General

Re: 29 Hours for a single print ? - 11 years ago
My longest print is 30hrs 43 min and I did run run out of filament in the last 4%... however I was there to pause and switch out rolls. It's what triggered this idea actually (see below link). I'd say before starting such a print you would want to clean and lube any friction surfaces you have. If you have overheating issues then you would have detected them with a 4-6 hour print as well, unlessby cfeniak - General
Re: Use an Opto stop to pause print when filament runs out? - 11 years ago
Would there need to be any change in logic if switching to a mechanical switch due to the high/low open/close difference? Never noticed M43 before, sounds up to the taskby cfeniak - General
Re: Use an Opto stop to pause print when filament runs out? - 11 years ago
Initial tests... awesome. So I used the Z axis max endstop location since I don't use it. Changed pin.h like so (I have Ramps 1.4): #define Z_STEP_PIN 46 #define Z_DIR_PIN 48 #define Z_ENABLE_PIN 62 #define Z_MIN_PIN 18 #define Z_MAX_PIN 19 #define PAUSE_PIN 19 And followed LAZYMONK's advice above with two changes. The first one was that the vby cfeniak - General

Thanks, I'll try this out today after my current print finishes. Let you know how it goes.by cfeniak - General
Re: Use an Opto stop to pause print when filament runs out? - 11 years ago
It could be done with a mechanical endstop as well, but I think an opto endstop would be more elegant. I have a reprap discount LCD to control my printer and have used the pause function to switch rolls. Hopefully this appeals to someone more familiar with the coding in Marlin, so that the right code and pins could be utilized to send a gcode pause on endstop open.

Re: motors getting hot? - 11 years ago
Hot yes, but probably not that hot. Are you printing much faster than defaults? I suspect you may need to tune you stepper drives.by cfeniak - General
Use an Opto stop to pause print when filament runs out? - 11 years ago
Does anyone know if someone has use an optostop endstop to send a pause signal to marlin? I am currently only using 3 of the 6 endstop locations on my ramps shield and was hoping one of the remaining three could be configured and coded to trigger a pause command when filament is not present (place the filament going through the endstop right before the extruder). Any suggestion or advice? Thisby cfeniak - General
