Thank you very much for step by step.
Glad it was helpful! 😊
Thanks so much for making this video! Please keep them coming!
Glad you found it helpful! We've got a bunch more planned, stay tuned!
Excellent video with fun. thank you dude
We're glad you enjoyed it! We appreciate the compliment! 🙌
Great video, you made it great by telling us the steps then demonstrating the steps. a thought for a future video, multi bits, multi projects(G54, G55...) using same bit on each job. Can demonstrate same job done on this video x 2(3...)(as an example). This would be set up doing multiple jobs with fewer bit changes and reduce over all time.
Thanks Stephen, we appreciate the kind words. Great suggestion for the future video, we'll absolutely add that to our list!
Great video, however, if your CNC is using belts, changing your bit can actually cause the head to move (that is vague i realise). If that happens, a complete homing can be helpful between cuts but totally depends on your setup.
GREAT video!! can you show this for the original touch plate? or is it the same process just flip over and let it hit the plate?
Same process! Make sure you have the original touch plate selected in the settings and you'll be good to go 🙂
Does the Longboard controller support a tool length probe for saving all the files together and just loading tools and having them touch off when needed??
Something similar to the C3D Bitsetter or the probes you can use with the Masso controller???
The new SuperLongBoard we're working on we plan to have native support for tool changing which we're really excited about, but due to grbl limitations the LongBoard and actually also the Carbide 3D controllers can't process tool changes on their own, Shapeoko machines do it via their Carbide Motion g-code sender and our LongBoards can also do it via our gSender open-source g-code sender 👍
Nice video, what if the roughing phase takes the initial material out, what is the best place to setup the Z axis in this case? I just use the top of the material left but it feels like there is a better solution that I can't get my head around.
If you know you're going to disturb the surface that you're zeroing from, you can always change the setting to "zero off the machine bed" (your wasteboard). Some people do this anyways, it's a per project/person preference!
Ah, perfect. I completely forgot about that option. :) @@SienciLabs
So glad we could help! Happy carving!
Can you please explain how you would do this if you did not have a touchplate? The first step in the process getting x and y to zero using the paper method is the mystery to me. Can you help? Thanks and Im hoping to try carving those Christmas ornaments when I learn this!
Yup, keeping in mind that you'll be "eyeballing" your bits location if you don't have a touch plate. There's nothing wrong with dong it this way, a touch plate just helps eliminate the guesswork.
-Load your first bit into the router.
-Move the router down until it's close enough to the material surface that you can line it up by eye for X and Y in relation to the material
-Grab a piece of paper and slide it between the bit and the material
-Using the "precise" jog setting, start lowering your Z axis while simultaneously sliding the paper back and forth just a little
-When the paper starts to get pinched between the bit and the material you'll feel the paper not sliding as easily until it can't slide at all
-At that point stop lowering your Z axis, click "zero all"
Hope this helps, please share whatever you make to the socials so we can all see!
@@SienciLabs Thank you for the reply!
So, if I start with a 1/4” straight bit, move to the lower left corner, bring t he bit down and lower to paper as you said. I would then zero all? So my x y and z are all zeroed out there? I thought I would have to bring the bit to below the workpiece on each side then zero x amd y.
Sorry, a bit confusing for this grandpa, but Ill give it a shot!
Thanks again!
glad we could help! If you run into any trouble let us know! Good luck!🍀
