@droftarts hey, Ian, welcome to the show, what is a "retrograde step?"

@mac @fcwilt you had the z probe working. Using an endstop on the low end is a retrograde step.

Ian

In your opinion. I see it as a distinct improvement.

X and Y can be homed with no Z movement required.

And generally Z homing can be faster.

But that is just my opinion.

@fcwilt @droftarts oh my god! what have I gotten myself between and betwixtd?

@mac said in I could use some help:

@fcwilt Z's going backwards. When I click on Z+0.5 it goes DOWN.

Then adjust the M569 for that Z drive and change it from normal to reverse or reverse to normal - the opposite of what it is now.

Re-boot and re-test.

@fcwilt

M569 P0.3 S1                                       ; physical drive 0.3 goes forwards

@fcwilt so I'm thinking I should change the S1 to S0? (I don't know that 0 means reverse, or the opposite of, I'm just surmising that's what I should do).

@mac said in I could use some help:

@fcwilt

M569 P0.3 S1                                       ; physical drive 0.3 goes forwards

So you don't know what to change?

OK here you go:

The P specifies the driver number which you have as 0.3 which sounds fine.

The S specifies the direction with S1 being normal and S0 being reverse.

Don't get hung up on normal and reverse - there really is no standard for what rotation is considered normal and what is considered reverse.

So since you have S1 change it to S0, re-boot and re-test.

@fcwilt nice to have that fan stop rattling away. I'm glad I figured that out, and thank you for the additional information. I was thinking of that song, One way, and another, when I read about there being no "normal and reverse."

@fcwilt look at his bed. It’s not 10mm cast aluminium plate, well-constrained and moving on linear rails. It’s a (please forgive me, @Mac ) cheap bedslinger setup. He’s going to need mesh compensation to have half a chance getting the first layer to stick. The probe was working fine. Fiddling around with a Z min endstop is excruciating with flimsy beds.

Doing kids bath and bed. Not around for a while.

M569 P0.3 S0                                       ; physical drive 0.3 goes forwards

Why is it never easy?

@droftarts kids need their Dad, I had 3 (they're all adults now, although the oldest is living with us currently). Thank you for being so helpful Ian!

@fcwilt are we okay even though the code still says "forwards?"

Everything after the ; character is just a comment - it affects nothing - you could put a line from a Shakespeare play there and it would make no difference at all.

All that matters is you find the right S parameter so the Z axis moves in the correct direction.

And the same is true for X and Y - if it turns out they are not moving in the correct direction.

Rest assured Mesh Bed Compensation will be implemented.

One small step at a time.

@fcwilt got it, I've offended you. Please accept my apologies. I've spent 70 years making life miserable for others. It's hard to get out of that habit.

A Former User

@fcwilt I'm not opposed to buying a decent bed. Given that the one I have on this printer now has failed the PID tests horribly, I'm looking for a good bed. Any recommendations you can provide (preferably links that will make you some money), would be appreciated.

I'm not offended at all.

I'm glad we are making progress.

I hope we can get Z working.

If we can do that, I think you can get X and Y working on your own since the issues are the same and the homing code is pretty much the same, just specifying a different axis.

I am running out of time today though.

@fcwilt My BLV rebuild of my old Anet A8 had linear rails. Marvelous kit, those. I still have them, and putting them on this POS seems possible with a little elbow grease and a drill press (both of which I have).

A Former User

@fcwilt got it, ship me the X and Y code please. I'll test Z right now to confirm that the changes accomplished what I may have to use to correct X and Y if they aren't up to snuff.

I know very little about your type of printer. I know that some popular models have upgrade parts available from different sources.

I just upgraded the bed on my E3D Tool Changer printer with a bed from Mandela Rose Works (I think that is the correct spelling).
