How to Surface Your LongMill Using gSender

Surfacing is a basic skill all CNC users should learn for flattening materials and your work surface. Now with gSender’s built-in surfacing functionality, users can quickly and easy set up a surfacing job.

Just setup and surfaced the waste board on my new LongMill MK2 30x48... ready to get carving on some projects. I have been very impressed with everything at Sienci Labs so far! Very helpful team of people, support and well engineered / manufactured products! Great job Sienci Lab team!!! Thanks!

[@Chaosweaver-1]

Didn't know gsender had this feature. Makes surfacing much easier and efficient.

[@michaelbruner3555]

I got to tell you that the Surfacing section of gSender has REALLY improved since I got my machine last March! Keep up the great work!

[@scottennis3397]

This video came in the nick of time, this was the final project to complete my 30x30 build! So appreciated, clear concise, and answered all my questions! Thank you Sienci!!

[@rotorrabbitfpv]

Great video! Very helpful! Thanks!

[@Dugsin503]

Thanks for great video. It’s always a good to refresh processes we don’t always use.

[@ca8920]

Great video and information. Thanks.

[@PorscheMonster]

Awesome video!

[@SienciLabs]

Glad you enjoyed it

[@bfreebabi5398]

Can you please make a video about Remotely controlling the Altmill by using the XBox Elite Series 2 Controller in GSender, how to connect the Controller

[@larryrobinson7492]

It's a great feature for the beginning user. I don't like the ramping dance or perimeter move. I wish that part was a enable box. I just usually manually write my own Gcode to do a quick surfacing or profile passes. I just want a basic lead in, Raster, then lead out, simple to write in Notepad or Wordpad. Cool feature no doubt.

[@leighredfern9783]

Great video mate

[@smokeebeefpv]

Great video. Thanks!

[@dwaynejohnson7499]

Great video I was playing around with the surfacing option and was planning on doing this in a few days, how long did this take for the entire surface. I have a 1 inch surfacing bit, about how long will it take?

[@SienciLabs]

It'll depend on how fast your machine is running, but I'd say 10-15 minutes roughly.

[@pipercub45]

How do you use the "Test Run" function?

[@SienciLabs]

You can just press the button in gSender and it'll check the file for any obvious errors in the code

[@pipercub45]

So it doesn't create any movement in the machine? Thanks@@SienciLabs

[@SienciLabs]

No movement, if you want to try the machine moving before you cut you can always set the Z zero high above the material and keep the router off, then run the job and see how it looks

[@josephvitale4357]

My LongMill is arriving this week. I built a table and plan on using the MDF slats like in this video for the waste board. I have a basic question should the LonhMill be mounted at the same height as the waste board or is it ok to mount it flush with the table which will be in my case 3/4 inch lower than the wasteboard?

[@SienciLabs]

It's up to you Joseph! The mounting difference won't make a very large impact on machine rigidity - the machine is instead flexible to how people want to use it, that way you could even use very large spacer blocks to raise the machine up and fit much thicker material under the CNC

[@ramijali6964]

Brother when I was upload surfacing program it has been going one line and suddenly stopped and showing grbl 1.1h for help. I can't understand what happened.. Please send me feed back.. Thank you

[@ryancampbell4847]

When you are surfacing, and it asks for the bit diameter (you used 22mm), are you measuring the surfacing bit where it cuts? For exanple, in the video you use a 1" surfacing bit, but the number you input is 22mm (not 1 inch). Where are you getting the 22 mm from?

[@SienciLabs]

The bit diameter you should set should be the exact diameter that you measure from the surfacing bit of where it cuts. The bit that I was using is a 22mm wide bit, it is not a 1" bit.

[@b-rad-1692]

Why when pressing stop job does all axis zero out?

[@PaulSchuster-yj4zb]

How could you do this for real on the small piece considering clamping it down but the clamps would be in the way?

[@SienciLabs]

You could use "side clamps" or super glue and tape methods so that you can still surface the whole top of the material 👍

[@kevinfinney8849]

well done!

[@loratian3]

Very cool

[@brianlister6036]

is GSender included with the machine when purchased ?

[@SienciLabs]

Yep!

[@josephvitale4357]

Excellent video. Thanks. I am considering buying the Longmill MK2. However, I just noticed something that concerns me. The gSender software expresses measurements in this video in mm. I hope that this is configurable to imperial. Is it? Is that true in all the software ? Thanks

[@SienciLabs]

Yes if you change your workspace settings in the gSender settings, the tool will work and show in imperial as well.

[@JackInTheShop]

nice

[@reddsmorris7053]

Sorry I am Dyslexic and find this very confusing on how to surface my waste board. Just starting out and need my board to be flat to the router.

[@squamishstu]

Do what he did step for step, pausing the video as needed

[@Life_of_John]

Jeez, that machines noisy!
