Marlin to Smoothieware

Skantron_SW · August 17, 2014, 5:08pm

Hi All, I have a Ultibots MK delta kit that came with a RAMPS board, but I wanted to try a 32bit board as it was said to overcome some of the ridging artifacts that deltas get with Arduino based systems. I have the settings for Marlin for the printer, and am trying to adapt them for the smoothieware delta config to run on a Azteeg x5 board.

Mostly, I think I have a handle on it, arm length and radius being the big ones, MM/sec converted to MM/Min. Some settings I am not sure about either what exactly they do, or what they should be set to, so if there is any insight people here have to offer I would greatly Appreciate it.

delta_segments_per_second is default 100, I had it set in Marlin to 200, should I set it to 200?

junction_deviation 0.05 in Marlin - #define DEFAULT_XYJERK 2.0; this seems much much higher so what would the equivalent be?

Stepper Motor currents, what is a good baseline for a Kysan NEMA 17 Stepper Motor? is this a setting that needs to be calibrated?

Also, the thermosister for the heated bed I have is I believe 100K QWG-104F-3950, but on github, I couldnt find a list of compatible thermosisters in src/modules/tools/temperaturecontrol/TemperatureControl.cpp:64.

Any advice would be appreciated. thanks

There is absolutely nothing to be gained setting delta_segments_per_second to a value greater than 100, you can do it but there is no gain and things will be slower.

junction_deviation is NOT the same as JERK, I’d suggest leaving it at the default value for now.

I set my Kysan steppers to 1-1.2 amps. They do run a tad warm at 1.2

Look at the current wiki page for temperature control. You only need to set the beta to 3950 for your thermistor, looking at the code is an old suggestion and is no longer relevant.

That is presuming the beta for your thermistor is 3950, check the data sheet for it.

Thanks, I was able to try out these suggestions, I left the Junction Deviation and Delta Segments at default.

I tried using the PID tuning for the Extruder, but is there is a similar setting for the PID measurements for the heater bed? (is using the BEta value preferred? I thought the PID tuning seemed like a neat idea, but maybe I don’t need to use that).

So I think I have something wrong in my Smoothieware settings, While printing a test 30mm cube, the side nearest the Z pillar is 30mm, but the side opposite is about 1mm short, so it prints trapezoidal (possibly with a slight cupping of those two edges as well, hard to tell). So, I double checked with my Marlin/RAMPS board, and that prints the same file fine. Is it possibly my delta radius is way off? Something else that may cause that?

Thanks

So, as I said, I tried again with my marlin/RAMPS board and I didn’t have any trapezoidal distortion. So, I am pretty sure I have an issue with my software/config, rather then a hardware issue. I double checked my settings, and can’t figure out what I have messed up, maybe somebody could take a look?

and for what it was worth my marlin delta settings were

Thanks in advance for anyone that has an idea of what is going on, I appreciate it.
