; Axis Limits
M208 Z0 S1 ; set minimum Z

Just a thought... If you're setting the axis limit with M208 to Z0, you can't go further down with babystepping. I have my M208 to M208 Z-0.2 S1, which allows for quite a lot of adjustment of the first layer with babystepping. As you're having particular problems with getting the first layer low enough, I wonder if this settings also impacts setting the Z datum.

Hi Ian,

I’ll make that change and recalibrate 1st thing
That makes sense.

Appreciate the help.

Cheers

Danal

Did I read somewhere that you switched to Hyaden Mag arms? (Which are great, by the way). What was printed on the stickers that came on the arms?

I see one problem immediately. A bunch of commands in homedelta.g have been commented out. There are two problems with that:

First, the "second pass" slow home is commented out. This means that tower height, and therefore indirectly bed height, is dependent only one a single bang into the upper switches that occurs at F1800. This is not very repeatable or accurate.

Second, after that single bang, there is not a slight downward move (it is commented out). This means the carriages and effector are "trapped" up against all three switches and cannot adjust for tower offsets or angles. This will produce all kinds of bizarre behaviors. The macro just ends with the carriage sitting there up against the stops. Depending on what the next move is, various weird things are going to happen.

Your homedelta.g should be:

Or very similar...

I will keep looking.

Danal

I notice there is an "m501" near the end of config.g. This loads /sys/config_override.g. Please either post that file, and/or consider taking the M501 out until we get this all straight.

That looks really odd to me. Can you post a couple of pictures of the printer? Preferably with the effector as close to X0Y0Z1 as you can get without damaging anything, and then one or two different photo angles at X0Y185Z1.

Thanks!

Hi Danal,

Yes I did fit Haydn mag arms length 440.47 mm

Thanks

Hi Danal,

These are commented out in the home file for Delta Calibration as per the documentation they are not always commented just at the point of posting.

Thanks, excellent stuff, I will take a look at all of that.

Just to triple confirm: The running file on the printer is going to end with the carriages (approximately) 5mm below the endstop switches, correct?

Carlo

@Danal

Hi Danal,

That's what it's supposed to do but I cant confirm as it homes to the below error so it doesn't bounce.
It used to do as intended but I rolled the firmware back redid the configs via the online tool since these errors.
Note* the height Z-50 is myself trying to move the effector after homing.

Not sure this helps.

Thanks I know its a lot to scan through it is appreciated.

We will get it going. I appreciate your patience in re-posting stuff for the "new guy" looking into this.

@Carlo Your active high endstops are incorrect, should be M574 X2 Y2 Z2 S1 ; Set active high endstops.
It also looks like you have both RR3 and RR2 configs in your config.g ? file

Good catch! Though you mean 'high end' endstops, as in their position on the printer; the S parameter is for active high/low (describes how the microswitch works).

yes correct, which version of the firmware is being used? as it's confusing
