Cramberry Pi case lol. Nice work! My builds so far include a large format Diode Laser and what is hopefully going to be a marketable yet CAPABLE desktop CNC machine called Lil Beasty.
Looks absolutely fantastic. I built mine but am having several issues. Where did I you learn to do this? If you could email me I would love to pick your brain on how to accomplish this. My Lowrider CNC Drops without power, I don’t have stops or ways to level it. The auto home heightens one side which stretches the Spring Screw on the other side. I could go on for days but am looking for someone with the know how and can do that can point me in the right direction. Again great rig and bet you are already putting that to great use.
Hey Larry, love this build you have made. Wanted to find out where you found the endstops models? If you designed them yourself would you mind sharing them? Find the designs very elegant.
Nice design, I thinking to use similar approach for X axis but most of the routers have vertical arrangement of linear guides is there any advantage. any disadvantage in horizontal arrangement.
Hello Larry! thanks for this Video. Can you make another video of how you set up your raspberry pi with the touch screen and I noticed you can control the low rider through the touch screen, I wonder which image you are using on the Pi? thanks in advance
I'm not sure that making a video of that is going to be easy or even possible (since I've lost the password to my lowrider's pi), but what I can tell you is that I used a regular Raspbian Lite image, installed X and cncJS on it, and under that, installed cncjs-web-pendant (you can google that, it's on Github). Then I added some startup scripts to automatically launch the browser to the cncjs-web-pendant URL on localhost. There's nothing super-difficult here; it's just requires patience. If I do redo that image at any point, I will video-document it next time.
Out of curiosity, which 3D printer did you use to make the frame parts? I would like to build this but the 3D printer is part of this process. Very nice clean build.
Absolutely sweet setup! I'm interested in this machine but have a couple questions. I'm interested as to more information about the electronics. I'm an electronics engineer by education but haven't ever looked at Arduino and Ramps. Do you have a quick layout of these and how they're used with the Pi? Also, is there a way to easily break this down so it's not taking up floor space in garage?
The RAMPS board is a "hat" that you attach directly to the Arduino. The Pi is only connected to that by USB. I am running cncJS on the Pi, and I also added the 7" touchscreen which you can get on Amazon. Then I added the "cncjs-web-pendant" software (found on github) to that so that pendant would display on the touchscreen. Somewhere on this thread is a link to the display mount on Thingiverse which will point you to the items on Amazon.
Oh, and to answer your question about breaking it down....... Some people have made their table fold up to a wall. Others have theirs fold up horizontally (sorta like a Mazlow). I'm actually in the process of making a cart that will allow me to fold the table up vertically and wheel it over to a corner of my garage. I'll post a video of that if it works out.
Awesome build, so I have 2 questions; 1- What is the effective size that this machine can do? For instance, if I have a 4x8 "table", how big will it cut? I assume something like 40x88 or so due to the router size and whatnot. 2- Can we have the gcode for the autosquaring/leveling? This is a neat feature and I'm certainly going to be making use of that!
The metal extrusions you used, what do you call those? they are like sliding door tracks or something right? Or is it just like steel C channel? Just wondering how that's worked for you as I was looking for an option to use metal to ride on instead of wood as I don't like the idea of wood, while MDF doesn't shift much it does shift some still and on top of that it'll wear down pretty easy even with minimal friction.
It's called Unistrut. It's in the electrical section of most big box home stores like home Depot or Lowes. I've since removed those from my table and replaced it with V-Slot which my gantry now rides on.
@@Dougie085 yes that's that stuff. We'll see what happens. I tried the cheap linear rails and had no real success getting them to glide. The V-Slot rails glide nicely. I'm still learning all of this. We'll see what happens in practice.
@@Dougie085 nothing wrong with the Unistrut itself, but the skate wheels wandered. So I went with guides for a long time. The guides worked, but I wanted to fold my table vertically for storage, and I had devised a method to lock the skate wheels down, and it worked great up until one of the locks broke and nearly destroyed my gantry. So.... I decided to put the thing on tracks of some sort and here we are.
It hasn't made any chips yet because it's got a Y-axis wandering issue that I am trying to solve. The limit switches were a bit of a project unto themselves. Time consuming to wire up and get the firmware dialed in, but well worth it for repeatability in my opinion.
Hi Larry - great build! I am building a similar set up currently. I assume you used the mpcnc grbl firmware as a starting point (github.com/johnboiles/grbl-Mega-5X/tree/mpcnc-rambo-support), outside of reassigning the additional two axis in config.h to account for the dual Y and Z steppers in the lowrider, did you have to make any other edits to re-assign the axis/endstops? Any way you can document the set up or firmware on thingiverse/github or the v1 engineering site?
I did in fact start with that, yes. It wasn't all that difficult. I set it up on my test bench and had it all working within in a couple hours (although I have to say emulating the endstop switches manually in a way that won't throw GRBL into an alarm state is somewhat of a challenge).
@@larrywimble2131 I assume that do you use 4 axis=X2, 5 axis=Z2. And do you used endstop pins as follow X1=Xmin, X2=Xmax, Y=Ymin, Ymax=unused, Z1=Zmin, Z2=Zmax. Is that correct? I have spend a week to figure out and still straggle, alarm alert but i don't know if i have everything wired correctly can do you share more details please. Thank you very much for your answer.
@@kristianpraslicka3669 In config.h, I set N_AXIS to 5. Then I set the individual axes in this order: XYZZX (the long axis on my machine is X, not Y like most others). Then set $3 to 0. This is important. If you have any motors running the wrong way, just flip the connector. Following that, you can set the bits in $23 to reverse direction for any motors that you want to home in a different direction. My limit switches are set to normally closed. I do not know in what order they are connected to the RAMPS board, but it's not hard to figure out just by depressing a switch and seeing which axis limit switch triggered by issuing a '?' command to GRBL.
@@larrywimble2131 Thousands time thank you!!! It worked finally, just it was need to also edit home cycle for 5 axis. I was just overthinking with endstops, masking, cpu_map adjusting and it was so simple, no inverting of endstop needed, just what you wrote. Thank you for your reply again!
Excellent! Thanks for sharing. I’m in the build process and looking forward to trying to match your progress.
I am really impressed by the setup you made! I am trying to do the same because it fits my workspace
That’s an awesome set up! Very Clean build. I Might need to upgrade mine with end stops after watching that auto square.
Really nice build!! Would love to see more videos!
Thanks!
very nice design. The homing firmware is genius. Can't wait to see you making chips, wood or alum.
Great job! This looks amazing.
Thank you so much!
fabulous effort
Thank you sir!
Well done!

wondering why you not have C Channel running each length of the wheel track that encloses each wheel to avoid dust collecting on the track ?
Can you point me in the right direction for the Rasberry PI and display?
hi any chance you can make a video how you setup the raspberry pi, and the arduino
I like your belt tensioners and endstops. Any chance you have the files available for others to print?
www.thingiverse.com/lwimble/designs
Sweet build is there any chance you could supply your stl you used for the endstops?
Sure thing, look through the comments, the link is there. I'll add it to the video on the next few days

Out of curiosity, which 3D printer did you use to make the frame parts? I would like to build this but the 3D printer is part of this process. Very nice clean build.
I used a Creality Ender 3. You can pick them up on Amazon for about $230 USD. That said, you could use most any 3D printer to do the job.

Nevermind the size question, I saw the "calculator" on the website. I have yet to find the autoleveling/squaring gcode though.
Super impressed Larry! I've been thinking about making a lowrider, can you share some of your mods?
Thanks! If you look through the other comments, you'll find the links. I'll compile them all this week and update the video description.

Awesome build, do you happen to have the dual endstop mounts files you can share.
I will try to get those uploaded in the next few days.
Looks really good! Can you show us some Chips?
Also were the 5 limit switches tough to wire up and program?

Omg can i please have a copy of your firmware, i have a lowrider 2 cnc and wont to dual z home up and z probe donw

Anybody else notice the mpcnc in the background?
Good catch! That unit has since been disassembled, but is waiting reassembly in a smaller form factor, probably as a laser system.
