Question about multiple heightmaps

@o_lampe said in Question about multiple heightmaps:

to me it seems, you have to probe the bed with S0 and then use S3 P"name.csv" to store it under a new name.

Correct. Send G29 S0 to probe the bed and save it as heightmap.csv. Then either rename it within DWC, or save it again under a new name using e.g. G29 S3 P"myNewHeightMap.csv".

@fcwilt I'm on 2.05 firmware and I plan on just putting the command in the start code in my slicer to choose which heightmap I load. I make different printer profiles based on nozzle size already so I'll just add extra ones based on the build sheet I'm using for each print.

I've been to chicken to upgrade to 3.x firmware and relearn all the config stuff..LOL.

JamesM

@dc42 @o_lampe Gotcha.

Positioning the removable build sheets is easy and I'm not worried about getting them lined up.

Thanks.

I put off upgrading but as I read about what was needed I went ahead.

It was easier than I thought with just a few changes needed.

I am VERY glad I did - I suggest you do the same - I would be glad to help.

@fcwilt Maybe I'll give it a shot tonight. If I want to downgrade back to 2.05 how difficult is it? Can I simply just have two different SD cards and swap it back or will uploading 2.05 through DWC do it?

Nowerdays the config tool is doing the job quite well.
Be a brave chicken...

To update to RRF3.3 you first have to go to RRF3.0.
It's good to have the old files on the backup sd card and have a clean install.
If you have some patience until we have solved eventually problems, downgrade is not an option.

@JamesM :

downgrade is not an option.

All joking aside, you can do this by uploading the zip file of the old version. Then restore the old files or in your case swap the card.

I was able to downgrade from one v3 release to another but I never tried to downgrade to a v2 release - I never wanted to - you won't either.

If you want to ZIP up all the files in your v2 system folder and post it here (add .txt to the existing .zip extension first) I will take a look. I might be able to quickly convert them for you.

@fcwilt I have made backups of the files already. I do that whenever I make changes and I zip them all using DWC and save them on my network drive. I'm actually making a full copy of the SD card right now to another SD card I have and then will start the upgrade process loading 3.0 and then 3.3 from what I read.

Then I need to set up my triple z files and whatnot after the upgrade.

Fingers crossed this goes smooth but I honestly don't think I'll see any benefit from 3.x since I don't plan on using any of the crazy new features. I'll do it anyway just to be current and then if it goes smoothly I can do it to my other 2 printers.

Good.

I think you be happy.

If you need help don't hesitate to ask.

@fcwilt Welp....how I did the config on the reprap configurator messed it up and now I can't connect. I picked a static ip address and after I uploaded everything and rebooted it now I can't connect. Time to bust out my laptop and connect to it via usb and try to get the wifi back on DHCP so I can connect.

New laptop too so I don't have YAT on it at the moment.

UGH.

Sorry to hear that. But if you know how to connect via USB you should be fine.

Did you use that tool to create a new configuration from scratch? Most of your old config was useable.

The biggest change I recall was having to create named pins (v2 had a fixed set names pins) using M950. The other commands that needed to reference to the pin then used a number that was assigned to the pin in M950.

There was a change in the way heater tuning was done but the process was the same.

I'm here.

@fcwilt I was just about to ask about that. I have a thermistor that I use to monitor chamber temps in my printer and wondered how the heck I set that up.

I'm using the thermistor that is normally for E1 for that.

My old line was M305 S"Chamber temp" P103 T100000 B3988 C0 X2

What I'm reading is that I now have to create a virtual heater first using M950 and this is where I'm getting confused.

Do I make a line like M950 H2 "Chamber temp" and then make my line M308 S2 P"e1temp" Y"thermistor" T100000 B3950 ???

Here is the part of a config.g file from one of my printers that deals with heaters:

@fcwilt I managed to get it working. Took me a bit to figure out what I screwed up for homing the y-axis but I had forgot to tell it home high in the configurator and had to change that setting and in the homey and homeall files.

Now to check everything on it to make sure it works ok and do a test print.

Thanks for your patience and willingness to help me.

Glad to hear you are making progress - it's easy to mess up a parameter or two.

Always happy to help if I can or to happily screw things up as well.
