This is something I hate sooo much. Imagine paying $100,000 for a lidar scanner, and then having to pay $7500 a year for the privilege or reading the files.

I have other motivations here too. As a business, mM might succeed, it might fail, but almost guaranteed in 15 years there wont be any new parts for the machines. The way lemontart is set up, you should always be able to get parts for it, even 50 years from now where were all dead.
this kits is kinda a posterchild for right to repair I guess. Buy, build, mod, upgrade with full support, do whatever you like.

Electrical is an issue, cause everything would need certifications etc. So at least for now, I will leave that to the customer out of necessity.


 

The password you setup for your user name.

What is the password to log in as a superuser?

Yes, that looks much better.

Can i use 5A Sanyo Denki 60mm stepper motors?
Jokes aside, very nice project and i do agree with you on leaving electronics out of the kit, to many choices and to many ways to mess up, still you should have a set with everything included whenever you get to that point as there are people that will gladly avoid wiring.

I'd thought I'd add samba and windows can be a PITA to setup.
As the underlying OS is Debian bookworm, any guides or how-tos that cover installing samba on Debian will be far far better than asking here.
I would also install gvfs-backends and gvfs-fuse as well. Samba-vfs-modules might be an idea as well.

The roadblocks with samba are all on the Windows side. You need to add a policy that permits the older version of SMB ptotocol.

Thanks. I’ll order the switches.

Having a blast is not my goal here. I need a working tool.

To be clear, when I set up the limit switches the software will treat the two Y motors as one? Currently they are being treated as separate axes, which makes it impossible to move the gantry to a home position.

Yes if you set up the home_sequence correctly. Read the link again another 3 times,,,,

yeah. i perhaps worded this badly.

There's 2 components. getting the basic UI all done up, and then what I guess is a really a wizard, with some preset options for recommended hardware such as jss (stepperonline) drives, delta ms300 spindle, etc

Basically I was a more full features wizard that covers modbus and ethercat. haha.

Thanks

Sounds interesting.

Stick the usb drive in, install, select a few options, run.

I'm afraid that is not going to happen unless everybody uses the same tested hardware.

This works fine for me.

 

Properly set up(motor directions especially), the homing will move both gantry axes (Y1 & Y2) until they hit their respective home switch).  Here is a configuration from my SO5 Pro gantry router I've been using for over a year.

Here is the program that is called for touchplate:
github.com/LinuxCNC/linuxcnc/blob/2.9/li...uchoff_subprogram.py

It's python code, but I think if you know gcode you could understand it.
Can you see what needs to be changed for your request? 

lemontart is a new CNC project I started on a whim last week and it all fell into place and the first one is hopefully being made NEXT week. That escalated quickly. EEK! I can't share a lot of final details just yet, but I can share the premise.

 

- lemontart is an OPEN SOURCE machine frame design/platform.
- machine kits will be available via miniMonster, but the cad files themselves will be GPL (or equivalent) so you could go about making your own any way you like.
- much like linuxcnc there will be a "main" build, and encouragement for people to make mods and accessories and share them.
- the design I see as a continuation of where the old xzero machines we meant to go before George got sick, but keeping a focus more on wood, vs metal like sorotec went with theirs.
- the first machine is the 57, which is 500mm x 700mm travel and geared heavily toward guitar making. Mainly hardwoods, plastics and light aluminium and brass work. It weighs about 240lbs as a frame, and the better part of 300 lbs built up, so its not shapeoko/altmill class (but also not miniMonster high precision class).
- the price of the kits will be VERY accessible especially relative to their performance.
- the kits will be 100% self assembly. literally a box with every single individual part, plus some special "tools" to make the job easier.
- the kits will come with basically every single parts except electrical. so you need to add a spindle, 60mm servos, wiring, electrical cabinet and a control
- I will be making video instructions on assembly to guide people though step by step, it should take an adept person a day or so to build.

So once these are out and selling/file available I want to work on a matching control and linuxcnc with ethercat is the obvious choice.

What we will need is:
- a nice UI that is preconfigured correctly for the machine/servos/vfd etc. it's own ISO perhaps? Stick the usb drive in, install, select a few options, run. a cosmetic skinning of qtdragon would be a great starting point here.
- jerk control. yup. Been tried so many time, soooo clooose..... but not there yet.

What I want to do is put a bounty on jerk control. I will pay the person that completes implementation of jerk control in a "finished" manner one lemontart machine kit. I don't care if its porting tormach's version, working on grotius's version, or from scratch. It just needs to be done and 100% bulletproof working. As I have said before so many times, it is mostly critical for G61 exact stop moves, and we should not get sidetracked by G64 smoothing things as they already have a degree of their own jerk limiting and linuxcnc's planner (especcially if the new tormach stuff is added) already performs very well (and more than good enough for lemontart).We just don't want the poor thing to shake down the building at 0.5g.

Probably wont be ready for the control phase til early next year, but if these things are in your wheelhouse chime in and give it some thought. 

 

I did a nother check in my BIOS and maybe i did annother improvement.
The ping performance looks mutch better then before.

Maybe this could solve the problem.
Fingers crossed...
