Prusa mendal I2 Pronteer face Marlin error

[printbus]

Once we know the driver boards are adjusted, my plan forward is to next test the endstop switches so we know they are wired and configured in Marlin in a compatible way. One step at a time...

FWIW, I totally agree with Mjolinor on his assessment of the video. I thought the same thing (some acceleration followed by an attempt to rotate too fast) when I saw it. Once the endstop switches are tested, I'd then suggest testing motors with just the X, Y and Z home buttons in pronterface since homing speeds are totally left to Marlin. After we see motors working fine there, you'd then test with the 1, 10, and 100mm movements on Pronterface. This last testing could involve reducing manual feed rate settings in Pronterface, not Marlin.

Hi,

How do i check the the switches are being pressed/released? is there some where that tells the status of these?

[printbus]

I'll help with that once you indicate the driver voltages are set. I'm glad to help, but want to stay focused on one aspect at a time.

Hiya, pretty sure i said in one of my last posts, sorry if i didn't, but all of the driver voltages are set to the recommended voltage in the manual, took a while to do that as i had to buy a new battery for my multi meter

OK. I thought the Y driver board was still being worked on. I now see I mis-read that.

How many endstop switches do you have? I assume three?

Make sure none of the switches are being pressed. From pronterface, issue a M119 command. This will read the endstop switches, as translated through the settings in the configuration.h file. What results do you get?

[jakers181008]

>>>M119
SENDING:M119
Reporting endstop status
x_min: TRIGGERED
x_max: open
y_min: TRIGGERED
y_max: open
z_min: opent (i'm going with this should be TRIGGERED..) same with when i set the values for inverted to false, they both go with TRIGGERED????.. any ideas this doesn't look right?
z_max: open

[printbus]

For now I'm not worried about whether the switches read open or TRIGGERED. For now, press and hold each switch closed (one at a time) while resending the M119. We want to make sure the value for each switch changes as you press and release that switch. If you have three switches, the values for the x_min, y_min, and z_min should be the ones changing.

Hiya, when i press them they change all but the 3rd one for Z :/


EDIT
Hang on a sec....

OK, let's try to get that fixed. There might be a wire broken between RAMPS and the Z endstop switch or the wires aren't going to the right terminals on that switch.

To prove the MEGA2560 board is working OK, try temporarily swapping the connector for the Z endstop switch with the connector for the X or Y endstop. Does the problem stay with the physical switch, or does it stay with the Z_min reading in the M119 results?

[jakers181008]

Okay before i had noticed one of the wires had gotten lose, but now when sending the M119 command it comes with:


Non Pressed
x_min: TRIGGERED
x_max: TRIGGERED
y_min: TRIGGERED
y_max: open
z_min: open
z_max: open


X Pressed
x_min: open
x_max: TRIGGERED
y_min: TRIGGERED
y_max: open
z_min: open
z_max: open


Y Pressed
x_min: TRIGGERED
x_max: TRIGGERED
y_min: open
y_max: open
z_min: open
z_max: open


Z Pressed
x_min: TRIGGERED
x_max: open
y_min: TRIGGERED
y_max: open
z_min: open
z_max: open




This isnt looking right?..


When i change over the X trigger to the Z pins, and i now press the x trigger (previously z) i get this:

X not pressed
x_min: TRIGGERED
x_max: TRIGGERED
y_min: open
y_max: open
z_min: open
z_max: open

X pressed
x_min: TRIGGERED
x_max: TRIGGERED
y_min: open
y_max: open
z_min: open
z_max: open
