Lightpath's Repetier 0.92 Upgrade Attempt

[Lightpath]

Ok, so this isn't so much a new build, my printer was going fine, but I wanted to incorporate the force sensitive resistor based z probing into my setup, and going with 0.92 seemed like the way to go.

There are several problems I'm having, but the two I am struggling with right now are:

When I do the hot end pid autotune it goes fine. When I do the bed autotune it gets to the target temperature, prints out the bias, d, min, and max, then it starts heating the bed again, and just sends the temperature of the bed through the roof. The hottest I let it go, just to see what happened, was 100 deg. I am using a SSR and a 24v power supply. The software looks like it is only powering the bed for 15 or so percent of the time, but the SSR is on solid. I would expect the SSR to blink quickly.

Here is what I'm using as a command to do the bed pid autotune:

M303 P1 S75

And here is an image of the resulting graph:

For your perusal, here is my configuration.h, I am going to try to keep this updated as I go:

Edit: Changed the rod length to 269

I've already spotted some errors in my configuration.h, I am going to try to keep the version I am using in the 2'nd post so I don't leave several wrong versions around.

[Nylocke]

Do you have 15 tooth pulleys? That's a rather obscure number for steps per mm. 240mm arms? I know EEPROM should override that but it's good to keep your config similar to your setup. Also, those are some weird probe positions. I set mine to 100mm spacing from center, right at each tower.

[Lightpath]

Hmmm... Which config option are you looking at for the 15 tooth pulleys? Mine are 20. If I search for 15 in the above I don't really find a pulley setting.

The 240mm arms are taken straight from the seemecnc configuration.h for 0.91.

I definitely have to update the probe positions. Thanks.

edit: spelling

[Lightpath]

Changed the rod length- You were right, the arms are not 240. I got the exact center-to-center value from the tricklaser website- I have the carbon arms.

[Lightpath]

Here's how I got steps per mm. From the seemecnc 0.91 firmware:


#define MICRO_STEPS 16
#define STEPS_PER_ROTATION 200

#define PULLEY_DIAMETER 10
#define PULLEY_CIRCUMFERENCE (PULLEY_DIAMETER * 3.1415927)

#define AXIS_STEPS_PER_MM ((float)(MICRO_STEPS * STEPS_PER_ROTATION) / PULLEY_CIRCUMFERENCE)
#define XAXIS_STEPS_PER_MM AXIS_STEPS_PER_MM
#define YAXIS_STEPS_PER_MM AXIS_STEPS_PER_MM
#define ZAXIS_STEPS_PER_MM AXIS_STEPS_PER_MM


AXIS_STEPS_PER_MM = (16 * 200) / (10 * 3.1415927) = 3200/31.415927 = 101.85916207406517

Is there something I'm missing...? The mechanics should not change from one firmware rev to another, but the calculations may.

As always, Mike, I appreciate your input.

[Nylocke]

Stock SeeMe arms are 269mm, don't know how you got 240? Don't use that calculator, use the one on the Prusa site, just search "steps per mm calculator RepRap" in Google. The 20 tooth pulleys should yield exactly 100 steps per mm with your motors and 1/16th stepping, not that 101.859162 that's in there now. Most likely EEPROM should have overridden this value, but if anyone goes of yours with a fresh install they'd have some weird effects. Most of those values in the config file I sent you should be spot on, mainly the PID tuning and Horizontal Radius, but those you end up changing in EEPROM anyway.

[Lightpath]

I took a fair bit from your file- It was great as a guide. I'll adjust the steps per mm. I agree it's an odd number.

I generally erase the firmware before reloading it. I like to start fresh, and I want to be able to depend on the numbers in the file matching what is actually being used. You are correct that the numbers are bad, it was behaving very wonky.

Edit: Oh, and I also rolled back to .91 for the moment, I need to print some stuff.

[Nylocke]

I tried to get everything spot on, unless you have an abnormal setup you should be able to use TGAT exact config minus the axis inversions, they might be off.
