Arduino Uno / Micro is better. GRBL has the pinouts predisposed and with a different card you would go crazy to understand where all the signals go. Technically it would also be possible but in practice it is a waste of time.
I also have a Tarantula, but I have improved it a lot (bracket, double Z, tmc2008, etc.) to have satisfactory prints.
Hi, I am currently working on the third video in which I finish the assembly of the pieces (belts too), the electronics and load the firmware. In the fourth and last video I planned to include the calibration phases and the filming of some works. If you have any doubts about the assembly, you can download the Fusion360 model and see the position of each single piece.
1. availability of material: in Europe the shopping bags are no longer made of LDPE, and they are so thin that it would take at least a hundred to have a useful quantity.2. strength: HDPE is a stronger materialfor these reasons I do not consider LDPE a viable choice for my home recycling. There are better (and easier to find) plastics
you can certainly do this too, but some time ago I tried and it is not easy to do a good job, the surface remained a little uneven. I also tried the heat gun but that tends to warp the piece, especially if it's thin. in the end I chose to finish with a blade, it is quick and I had no problems.
it's a silicone sheet, like those used to prevent food from sticking to trays
no, plastic is flammable and I would avoid putting it in the vicinity of flames for a long time. Furthermore, you would not have a control on the temperature, for example the PE melts it at 160 ° C but already at 190-200 ° C it turns brown and is irreparably damaged.

great idea, maybe even better than mine
nowadays most of the cutting boards are made of PP, even the European Union does not allow the use of wooden ones in the catering sector.
In my experience I have not encountered these problems, I washed the pieces of plastic and there was no odor left, neither before nor after melting the plastic.
1. yes, one for me and others for some friends2. yes, it's a portable oven
It's a simple electric kitchen oven, which I only use to melt plastic
Thanks, i took your advice and i changed the title ^_^

the measurements of the 2040 profiles must be set according to your work area; if you look in the description I have indicated how much to increase the profiles.
#define ENABLE_DUAL_AXIS // REQUIRED #define DUAL_AXIS_SELECT Y_AXIS // REQUIRED #define DUAL_AXIS_CONFIG_PROTONEER_V3_51 // Check if enabledcheck those lines. if the code is ok then check the wiring; swap the wrong engine with another, etc.
Thanks for your kind words.The pebbles have a shape that depends a lot on the origin, if they come from the sea they are thin and elongated, if they come from the river they are ovoid. A third possibility is that they come from quarries and subsequently rounded and smoothed by mechanical action until they resemble those of the river. The ones I use are almost certainly in the third category.
do you mean divider between the path and the garden? They are blocks of stone
Thank you. Compared to the old risseu, I dug about 15cm removing the roots that I found, the soil was sufficiently dense and it was not necessary to compact it more.Then I laid a 10cm reinforced concrete slab with a rebar steel mesh.My risseu is designed for the passage of people, bicycles and motorcycles but it can also be made suitable for vehicles, with some precautions: under the concrete slab it is better to lay a layer of gravel and it is preferable to use larger stones.The wheelchair does not create problems, not even for my risseu, but I suggest you use stones like mine, 3-5cm, and placed as close as possible to not make your son take too many jolts.
Thank you very much!
when I created the reinforced concrete slab I left a series of corrugated pipes inside the casting and then I passed the wires and mounted the underground lights. As SylvanB said they are a specific type of lights for outdoors guaranted for IP67 protection. I took a picture in the dark but unfortunately one of the lights was burned out and the only one I had to replace it was a warm light ... and obviously the mounted ones are cold :(
Thanks for spreading my project!
I'm glad you liked my project!
thank you! with a little practice it is not very difficult to position the stones correctly but yes, a lot of perseverance is needed: D
thank you! you are very kind. 6 hours per square are necessary for the laying of the stones alone, but it is definitely the most tiring part due to the posture of the body.

thank you! I'm one of the finalists, fingers crossed: D
You are welcome! I like it a lot too, especially the slender structures that can be obtained with steel elements.
Thanks, I am very pleased that you enjoyed my work. I believe that for workspaces as large as the ones you want the G300 needs some tweaking. For a net area of 1200x1200 you need profiles about 1500mm long and the 2040s for the Y tracks are too deformable, better to use the 2060s; for the X track keep 2040 but add at least another two to three central reinforcements. As already mentioned in another message, the supports of the Y tracks must be modified to accommodate the larger profiles while for the two Y carriages it is sufficient to use threaded bars longer than 2cm compared to what is indicated in the BOM.I recorded the entire assembly phase with the intention of publishing it on youtube but I didn't have time to do the video editing.To make up for this lack in the next few days I wil…

After all, having won the CNC contest and a cash prize, it seems fair to me to release the .f3d fileWith the Fusion design, the separate BOM per component and the written description of the various steps it should not be complicated to finish the assembly. If you have any doubts, feel free to contact me even in private.

The weight is essential to reduce the vibrations caused by the resistance of the material to be milled.Flex shafts are not suitable for CNCs: they are too light, generate a lot of friction (therefore they overheat) and do not allow the motor torque to be optimally transferred.They are only suitable for a dremel, where torque is limited, and for very short jobs.
Combining two codes is complicated and you can create bugs without realizing it, especially generating unwanted delays. By keeping them separate you know the GRBL will do its job without interference.With two separate Arduinos you can update GRBL without having to rewrite and check the second code, every time.For these reasons they are deliberately kept separate, the second arduino will be able to intervene on the one destined for GRBL only by sending a stop signal in case there are errors / damages.
the tip I used was not suitable for the job (V90 ° and flattened tip) but I am satisfied with the result and I will buy specific 45 ° and 60 ° cutters for the V Carve.feedrate xy: 500mm / s, z: 250mm / s, 2 passes. F-engrave software
but don't call it V2! will be the G300S :Dgatting serious againI am also a (structural) engineer and I know the properties of materials, PLA has a Young's modulus of 3-3.5GPa and it certainly has its limitations. However, it is not correct to make comparisons between materials based only on Young's modulus; eg Shapeoko steel plate is 3.42mm thick, other machines have 5mm aluminum plates, my little one has 10mm PLA plates.In terms of flexural stiffness (E * J), which for the uninitiated is directly proportional to the cube of the thickness, we have these results:Aluminum (68GPa) 8500, Steel (210GPa) 8400, PLA (3.5GPa) 3500.Certainly my CNC has a weaker structure but it's not that bad.

The Kid Clock / Une Horloge Pour Les Petits (Bilingue)
It is nice to exchange opinions and advice with you. :DI also noticed that some projects have undergone numerous revisions but I think it is an integral part of this hobby. If there is something wrong, you improve and learn something new. I almost appreciate the learning phase more than the actual realization of the objects ...If you look at the 3D printed parts, almost all of them are simply plates with holes, I have already used a very essential geometry, if you want you can already make them in steel. However, some pieces are easier to print than to work them in steel: the Z carriage, the reinforcements between 2040 and the 4 Y supports in the corners. I didn't want to put together too many heterogeneous elements and so I chose to do everything in PLA.
I only have the video of the construction of the decimeter grid but, despite manually using a vacuum cleaner, I filled half the garage with MDF dust. This weekend I will install the dust collector and then I will be able to film something interesting.
fixed, BOM is available now
