5bar scara Problem configuring z probe using fsr switch

[gnmrc_]

@fcwilt yes in the homing file I tried to use a dummy G92 comand to trick the machine in to moving, but with no success. There is something that I’m missing but I can’t figure it out.

So I wanted to build a SCARA printer because I think that there is a lot of unexpressed potential in this kinematic but due to it’s complexity there aren’t a lot of people that wants to build one of this printers and improve them. This type of printers are left in an embrional state, particularly the 5bar one, the only 2 guys that I have seen make them work are Joerg and Pontus Borg but 3/4years have passed since the last videos and post about those printers.

Thanks for the help,
Gianmarco

@fcwilt for semplicity of wiring I would prefere to have only the probe, but due to all this problems I’m really considering this solution.

I clearly misunderstood. I thought the G92 did allow homing to complete.

Just out of curiosity how about a test where the G92 for the Z axis is before the two G1 H1 moves. Then you could see if the G1 X0 Y0 move needed H2/S2.

If that worked once you could get to X=0 Y=0 then you could use the Z probe to accurately set the Z axis.

Thanks.

@fcwilt Nice idea, I’m gonna try and see if this trick works.

I haven't been much help so far.

To date what I have mostly done is help you to find new and interesting things that don't work.

@fcwilt It’s not true, we are trying to solve a problem that seems easier than what it really is on a complex and not so well documented machine. You gave a really big help trying to figure out what the problem is, and giving option on how to solve it.

By the way if you want to build one I can give you the cad files so you have the machine too and we can complete the build of a well documented and easy to work scara arm.

@gnmrc_

Actually I would like the CAD files - I'm always up for a challenge and I like new and interesting things to work on.

@fcwilt ok I’m gonna send it to you, but I have no idea in how to do it. Can I link them here in some way?

Are they large?

You can attach files to messages here but I don't know if there is a size limit.

Perhaps you can email them?

Or I have a DropBox account. Maybe there is a way you can leave them there. I would have to research how to do that.

@fcwilt Yes they are too big to link them here, the dropbox could be the best way.

Do you have a Dropbox account? I know how to share files (yours to me) but I don't know how to allow you to put files into my Dropbox.

Frederick

[gnmrc_]

@fcwilt no but we can use a google drive in the same way right?

I don't know. I have it but to do certain things you have to sign up for a paid account. It's not much it's still another $72 annually - minimum.

Do you have Google Drive?

Frederick

[gnmrc_]

@fcwilt yes, it would be simpler to link them there

This thread is a bit long now. Can you create a summary post of the issue as it is currently and I can pass it along to DC42 to see if he has any suggestions.

@Phaedrux do you have any news from DC42?

[Phaedrux]

@gnmrc_ Yes, can you please start a new thread with the core of the current problem. Include your config.g and homing file.

[gnmrc_]

@Phaedrux I have created the recap post this is the link.

[Phaedrux]

Thank you. With Formnext going on it may be a few days before DC42 can take a look.

[gnmrc_]

@Phaedrux yeah I imagine but I am not in a hurry.
