So if P7 worked, he must have his BLTouch connected to the Z endstop input; whereas P9 requires it to be connected to the Z probe input.

One thing I have noticed is that folks who are not good at attention to details often struggle with configuring 3D printers (and other things as well).

Aside from the occasional mistake they we all make from time to time it is clear you very much know what you are doing.

Thank you for your hard work, the Duet family of products has made building my printers so much easier and enjoyable.

@dc42

1 - END by itself is easy but if you don't see it in context you don't know what it is the end of. It might be better to have unique keywords - ENDWHILE, ENDIF or something along those lines.

2 - I would make the use of the new keywords mandatory. Yes existing users would have to do a bit of work but it would keep things simple and consistent for all in the future.

3 - While you are implementing the change I would also suggest that a REPEAT/UNTIL or a DO/WHILE loop be implemented - the type of loop that always runs once.

@kwad3d-0 said in BL Touch Issues... Again and Again...:

@fcwilt my height map looks better then that however still lifts off on one side by about 1mm. So You don't know what your talking about and are just trolling at this point. You have not contributed anything at all besides criticizing my terminology I use. I don't want you to comment any longer and be on your way now...

I think you are confused about who may be a troll.

But since you are so wise I'm sure you can solve this simple problem on your own.

Have a great day!

@alankilian said in My wish : Inputs debouncing:

Thank you for letting me get confused at times.

We all get confused, make mistakes, make assumptions, read things wrong, etc.

It's just the nature of forums.

Generally we as a group get it sorted in the end.

@dc42

I am very happy with RRF v3.

I did not find the changes from v2 to v3 as extensive as I first imagined.

As I have progressed from v3.0.0 to v3.1.1 to v3.2.0 to v3.2.2 I have not encountered any changes I had to make.

I did make changes to take advantage of new features but they were changes I chose to make, not had to make.

I am very impressed with the folks who are developing the firmware for the various products.

As in many aspects of life some few folks are hard to please and I see little reward in trying to.

Kudos to you all.

The last G30 P2 has F550 instead of Y550

Hi,

Here is a link to a quick-and-dirty video showing the mini linear guide at work.

Mini Linear Guide At Work

It was hard to get a good view - sorry.

Frederick

Hi,

It would be nice if you could add some white space at the left margin of the editor.

As it is the cursor tends to be hard to see when at the left margin.

Thanks.

Frederick

@apairofcleats

Just remember to follow the correct procedure.

You must first update to 3.0.0 then to 3.1.1

Upload Duet2and3Firmware-3.0.zip

When asked let the update proceed.

Upload Duet2and3Firmware-3.1.1.zip

When asked let the update proceed.

If all goes well you should be running firmware 3.1.1 and Duet Web Control (DWC) 3.1.1

Frederick

@cando415

You have this in your Y homing file:

G1 H1 Y+360 F6000 ; move quickly to Y axis endstop and stop there (first pass)
G1 Y5 F6000       ; go back a few mm
G1 H1 Y+360 F360  ; move slowly to Y axis endstop once more (second pass)

All three of those moves are in the same direction.

Based on the G1 H1 moves the G1 Y5 should be G1 Y-5.

Frederick

@phoenix

That's why we are here!

If we cannot help, we can mess things up in style.

Frederick

@phoenix

Before you can user a variable in the form var.some_name you have to declare it using the form var some_name = 0, or whatever initial value you want it to have. Notice there is not period character between var and some_name in the declaration.

Frederick

@gloomyandy

Yes, indeed there are.

I was speaking from my personal experience BUT as I have no intention of using the SZP for setting the Z=0 Datum, I have done no testing of that feature.

I'm "old school", I install BLTouch units for setting the Z=0 Datum.

Frederick

@vaike_peeter

It is confusing.

1. The closer the better in that the readings can be more accurate.

2. The farther the better in that you are less likely to have the coil strike the bed.

On my system I use 3mm - it seems to provide the required accuracy while being a bit more forgiving than 1 to 2 mm.

Frederick

@rodneysramosj

Having posted your files and looked at them I will suggest your homing code is needlessly complicated.

Three simple G1 moves (G1 H1, G1, G1 H1) should work just fine.

What is your reasoning for the complicated code you have created?

Thanks.

Frederick

@rodneysramosj said in After Homing will not manual Move away from endstop:

thanks for all the help on the last post, however... we are running into an issue after successfully homing in which we cannot manually move away from the end stop only towards it. I will attach the home and config files we are currently using. thanks in advance. config.g homeall.g homex.g homey.g homez.g

In the future please post things like your *.G files using the </> tag.

Posting links means we each have to download your files to look at them.

@rodneysramosj said in Printer Not hitting any of the endstops:

@fcwilt we got it to a point where it hits the endstops but it stays stopped on the endstops and doesnt come back out.

Does your code command it to back out?

Frederick

@rodneysramosj said in Printer Not hitting any of the endstops:

@jay_s_uk endstops are wired correct and they are triggering correctly through config. however, it is moving in the wrong direction now and in the opposite direction from the endstops. we tried changing it in the config tool from low end to high end and now they are currently swapped back after troubleshooting.

If the movement is not towards the end-stops you need to check your homing code to see if it is using moves in the correct direction.

Hi,

Did you read this?

https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_coreXY

It tells you what to do in each case where XY movements are not correct.
