Have you heard about GrblGru? A wing creator was added for foam cutting. This software offers some nice features like creating cuts from svg or dxf data. With that you can create custom cutouts for example for fuselage walls where the wingprofile must be cut out. I can only recommend it!
Thank you so much. Great job. Seems that there is an error in the description of the input for A-Min endstops, using a 2560 and Ramps 1.4 I'm sure of my switch as it works if I put it into an other "channel", i can see it switching like a charm. For A-Min I tried D49 and not working. It seems that the preset are fixed for D42 instead. By the way would it be possible to upload the source of the Mega2560 code, it would enable us to change in/out depending on our 'old wiring' For the software some color (ie especially for axis) would be nice, it would enable to 3dprint part of each axis with a color and refer to this color in the sofware, the no more error in moving an axis instead of an other. PS : if you need french translation do not hesitate, some of the implemented one are badly translated :-(
The firmware source code is the same as github.com/fra589/grbl-Mega-5X. The only changes are to set it for 4 axes and the limit switches. You can change it to suit your needs. Thanks for the offer of translation but I'm not planning to release any updates.
from the schematics i've seen for the RAMPS board it looks like you can only have up to 5A for the circuit that powers the stepper motors. Is there a way to increase this?
The stepper motors on the foam cutter use little current because they do not drive a cutting bit into the material. I use NEMA17 stepper motors rated for 0.9 amps and run them at 0-5 amps without any issues. So I wouldn't worry about it. Many guys have used the RAMPS board with great success with 1.5 amp rated steppers and have not had any problems.
Thanks for your response! So if I had 6 motors that draw 1.3A (dual steppers on one of the axes), would that mean I need a power supply of 7.8A and not be able to use the RAMPS board?
I can't see how you would use dual steppers on a foam cutter. The motors will not be running at full current so I doubt it will be an issue. If you are worried about current draw then use an MKS Gen L board with external drivers.
Yes thats sad, it was a beautiful build and the vc10 is eye candy when its just sitting there. This must always be an issue with working models, hours and hours spent put into recreating authentic detail when all that can be wiped out in a second. There is another vid on yt of a flying model vc10. Here the props are not in the cowling so can be bigger.
You can import the image. Have a look at this video where I import an image into Fusion 360 and then create a DXF from it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sq7Dfw7plzw.htmlsi=vZc_J3fM62kejy2t
Nice to see there´s a 3d-printz directory on your machine :). Thank you so much for your work Keith! Just wanted to let you know i´m currently cutting parts with the new software for the compartment of a medical delivery drone which operates in Malawi. So your work basically contributes to literally saving lives! thank you very very much.
I'm completely new to the CNC world so forgive me if my questions come up as someone naive. I managed to struggle my way through building a desktop CNC machine using v-groove extrusions. I purchased an MKS DLC V2 board that runs three TB 6600 stepper drivers. I'm using Nima 17 motors and open builds cam and control software. So far I've managed to get the machine to perform a dry run of a design I created in illustrator. Every step of the process so far has been quite the mental challenge. Slowly but surely I'm getting it figured out step by step. One thing I'm not is a programmer. All the programming stuff usually goes right over my head. But I can kind of see what happens when you change certain things in the grbl code. My current challenge is to figure out how I can get open builds to recognize the Wi-Fi module on the control board. Someone told me they were able to configure/install grblhal do the same bored and then open bills is able to recognize it. In the most simplest of terms could you explain to me how this might be done? I would greatly appreciate it. Thanks. Subscribed.
The MKS DLC V2 is an 8-bit board that doesn't have wifi. The MKS DLC32 uses the ESP32 processor that does have wifi support. I don't think it's possible to get wifi on the MKS DLC V2 because the 8-bit processor doesn't have enough resources to do that. If you really needed wifi then you'll need to change your board. To use grblHAL you need a 32-bit board. Thanks for subscribing but just to let you know I stopped making videos for the time being due to health isuues. Keith
@@rckeithsorry to hear about your health issues. Hope you heal up. I also meant to say that my card is the MKS DLC32 V2.1. it has the Wi-Fi module on it. But I'm so inept with electronics that I can't figure out how to get it to function with open builds control. I did find some information online about using MKS tool to configure Wi-Fi but the only version I could find was old and in Chinese.
Hello and thank you very much for sharing. I'm just starting to test my cards. I have a zoom problem on the Grbl software, I cannot see all of the software despite having changed my display settings. My screen is 1366x768. Do you have a tip for this please ?
Hello, I am currently building a 4-AXIS Arduino CNC Foam Cutting Machine. However, I'm encountering some issues. The issue I am facing is that in the GRBL Software, only 3 Axis are showing. The U axis is missing. Do you have any idea how I can solve this issue? It would be great if you could assist me with this. If you are interested, please share your contact information. I would be glad to connect with you.
Follow the instructions here with the latest firmware and software.rckeith.co.uk/grbl-hotwire-mega-5x-for-cnc-foam-cutters/ The U axis is for the older firmware and software

@@rckeith Thank you for your response. I am currently using an Arduino Uno. Is it necessary to use an Arduino Mega for a 4-axis system, or can I continue using the Uno?
Hello Keith, Thanks for all the lovely videos. Do you think you could make a version of the hotwire controller that works on Linux. Or atleast guide me (and others like me) on how to make one. Thanks
Hi Keith, new here and have been watching quite a few of your videos👍. I have Jedicut installed OK, but the preview screen shows the airfoil as a line 45deg. on foam block. Any ideas.
I am very grateful for you making this video. I have a k1 max, i am having problems with pla lw from e sun, they stop extruding in the middle of the print. Maybe is the cronical clogging problem, maybe is something on software (i use cura) but i will try your creality print settings and never give up hahaha. I only occurs with lw pla
Thanks, I'm afraid it won't be soon my health isn't as good as it was so it's looking like it will be much later this year. I've stepped back from RU-vid for a while as well.🤥
@@rckeith suggest me something about alignment the workpiece i want to get perfect alignment in x and y axis During operation right now I am unable to hold workpiece again in perfect straight line I machined and unclamps it and use it or do something else and then after i want to machine it again for some cuts and drills what ever Then how I align it perfectly it's very challanging for me right to align perfectly again and again after unclampimg and clamping there is giving minor errors in positioning perfectly Is it any rule or formula or tool for perfect alignment each and everytime clamps and unclamps the workpiece
Hello rc Keith, my co worker and I have been working tirelessly on our hotwire foam cnc. We are using ours to cut out tapered cylinders. The only difference that we have compared to yours is that ours has a turntable in the middle. Our problem started when we started to add homing and limit switches. The homing function only homes the uz axes then stops and then grbl freezes. We are using the mks gen L v1.0. any help would be greatly appreciated
You probably are trying to load a dxf file from a folder with a space in the folder name. Move it to a folder with no spaces in the name and it will work. It's explained on the download page.
The wire is powered from the board. The MKS Gen L and SKR Pico can use 24 volts and this is connected to D8. Yes you can cut many types of foam like XPS, EPP and Sytrofoam
Keith.. i have discovered the problem… after some consecutive cuttings (arround 3 or 4) the feed rate got crazi,,, i send a movement with 200mm/m but the grbl hot wire moves at 600mm/m .. so i close the grbl hotwire and repowering the mks board… so i cut fine… today i made a lot of cuttings this way, closing the grbl hotwire and repowering the mks board between each cut… i don’t know if the problem is the firmware of the mks or is in the grbl hotwire software… but this way i can made a lot of cuts witout problem.. i did take some pictures showing this if you want to see give me an email what i send you
Can you include the settings you have on the machine and the software you are using to generate the g-code as well as a copy of the g-code you are running. I will then take a look and see if I can see anything. The firmware is almost identical to the previous version for the MKS board only the axis letter has been changed. So I don't think there will be any issue with that or the software heavily based on the older software. I've run many tests on the new firmware and software without any issues. Keith
Hi sir! I did debug a bit der andere code to correct planer.cpp and get kinetics to work. I hope marlin works fine for you . For gcode generation I use jedicut. I am looking for a 4 axis version of octoprint… have you found anything like that?
Hi, I don't use the Marlin version for my foam-cutting projects. I'm using the grbl and grblHAL. Some guys didn't want to use a PC to run the foam cutter so that was the reason to develop it. I haven't done anything else with it since this video.
Hello, I appreciate your efforts and have a question. I already built my CNC foam cutter structure and have one stepper motor per axis (one for X axis and one for Y axis). I wonder if I can use your firmware and Windows software for my machine? Regards
@rckeith got it. You really did a perfect combination of software and hardware, I definitely modify my machine to work with your firmware, thanks in advance
@rckeith Hello again, I modify my CNC machine and successfully make it running. But after post-processing my plan in Fusion360 and loading it to foam cutter software, I've got an error in which the axis letters are incorrect. Probably because of the changes in U axis to A, could you please help to solve this issue? Regards
