Charlie,... just to say THANKS !!! for this tutorial,... I was more than two days trying to understand and figure it out how to configure the "A" rotational axis of my small 4 axis milling machine (an M70 Proxxon CNC adapted by me many years ago), it happen when I changed the main breakboard from the old parallel port type to an USB type. The most useful it was the Stepper Calculator Table, that I could not find it for download,... so I did my own table based on the hidden formulas in it (not too difficult to find out). Everything is fantastic now !!.
Charlie Sarsfield that's all good no worries! I've sorta figured that if I set my - and + to really large number of degrees I should have no problems with rotation limits as I really don't like operating my 6040 without soft limits on! I should really get some limit switches!! Thanks for your videos once again they have helped me so much!!! 👌🏻👌🏻👌🏻 take care!
Thanks for your making vids time - I see a few more folks having been stuck for quite a while. These machines are for using :-) (sais me @ about 15months ownership!!) As before, filehosting never sends the link to download the file - it’s basically not available. Thanks for mailing it to me. I’ll setup the a axis tomorrow as everything seem now to work! Soon be taking ‘the plunge’. Your flashlight looked good. I wonder what I’m gonna bust b4 I’m at your state of alertness regarding the various parameters - your method is worth observing - it’s not just a case of ‘the machine made it’ and with these machines in our hands, necessary to administrate well. Thanks again.
Rotation direction on CNC machines is viewed from one end or side of the machine, if you turn the device around 180 degrees it would be reversed. This would be true in any Axis left to right, up to down and front to back.
Hi Charlie, I just subscribed. Thank you for the video. I've been thinking about getting a CNC engraver like this and seeing the setup really helps. If you could do it again would you buy the same machine?
Clayton Musgrove Hello Clayton, no special drivers needed. Just plug in the WiFi dongle that comes with the keyboard and off ya go. Then use the Mach3 keyboard shortcuts. I did disable the onboard mouse as it caused a few accidental cycle starts.
@@hectorotani27 Ok. With the mentioned applications, you can still do contour engraving. No rotary axis needed. An example video of my contour engraving... ruclips.net/video/MucnmEtoEXo/видео.html
Hi Charlie, I'm looking at buying one of these machines thinking it's a good and inexpensive way to start my cnc journey. So my first question is do you like it? My second question is Who to buy from? The link you provide doesn't exist anymore and there's so many vendors out there. Thanks for any help you can give.
+Al Sadaj First, congrats on starting your cnc journey. It is a bunch of fun, in my opinion. Yes, I like this machine for a starter setup. I got mine through a USA distributor on eBay. And thanks for telling me about the dead link. I'll see what i can find, then update it. Till then, just look for a highly rated machine through a highly rated distributor. That should do you good. And have fun learning about cnc. It's a fun hobby.
Hi! I follow all the steps in the video but my motor lost position every now and then for example after 10 cycles of work the actual position it's moved 0.7mm from the original position. Do you know why is this happening? Greetings
Hi, I have a harmonic drive 4th axis with gear ratio of 50 to 1 do I enter this into the calculator? also how do I work out degrees and pulse per step? thank you Rocky
Yes, the 50 should be entered for the Gear Reduction. I would try 8 or 10 for the Micro Stepping, then see which Steps Per Deg will rotate the axis 360 Deg for MDI "G0A360". 1.8: 8: 50: = 222.2222222 "Steps Per Unit" for setup 1.8: 10: 50: = 277.7777778 "Steps Per Unit" for setup I would try these first.
+Rocky5738 It should, unless the DRO is already at 360 in G90 mode. Can you move the rotary axis via MPG mode (tab key)? Did you watch this whole video going through all the rotary settings?
Just unlocked Ang Short Rot on Go and I could just turn the 360 degrees, to automatically configure the steps. Before I could only turn 180 degrees in automatic configuration. You can tell me what that setting is for.
+Jose Chavezz Yes, with that setting on, when using G0, the rotary will make the move taking the shortest route possible. Example... In absolute mode (G90), if you are at A270, then code in G0 A0, instead of unwinding by moving -270, it will move +90 to reach the rotary position. In Incremental mode (G91), if from your current position you code G0 A+190, the rotary will move -170 to get there since that is the shortest route.
Thank you very much for this excellent tutorial that saved me a lot of time. I have managed to get my 4th axis running but I don't understand how to configure the values I have the stepper calculator and specs from rotary seller are 3.5A 4 lead 57 stepper motor(1.8 Degree Step Angle) MACH3 setup instructions: 1 degree required Pulse The formula is: 360 / subdivision stepping angle * Drive * Transmission ratio / 360 = MACH3 Pulse Is it possible to configure the stepping with this values, if so can you please tell me how or even better the values I have to put in mach 3 ? Thank you
Ok, In Mach3's Motor Tuning... try 20 in the "Steps per" field. As in the video, put numbers in the "Acceleration" and "Velocity" fields. After that, MDI the rotary "G0 A360". Take note of how far the rotary turns... 360deg... under 360... or over 360.
Ok, the steps per unit will be less than 20 in your case. There is a button on the settings page in mach3 titled "set steps per unit". It's at the lower left. Give it a shot. Tell it to go 360 deg and then estimate (if ya can't measure) how far it moved. Keep doing this until it's close to accurate, then we should be able to dial in the correct number. Let me know how it goes.
Hello dear friend .. I have a problem with my fourth axis, I can not calibrate it with the Set Steps per Unit to 360 degrees .. I can calibrate with 180,270, but when I place 360 it does not move the fourth axis and tells me the mach3; far moved axis A, when it did not move, something is missing configure. The first time I configure it if I calibrated it to 360 and then I made a G code that went wrong because I was in another unit of measurement I have this error. thanks for your support.
+Jose Chavezz Hi Jose, the steps per unit in this case is degree. in that field you input steps per 1 degree, not steps per 360 degrees. It doesn't matter if you are in mm or inch for this particular setting. When you get it correct, mdi G0 A360, and the rotary should rotate 1 revolution. Use the calculator in description to help figure the steps per degree.
I must say one of the best videos for rotary setup.I have a rotary Roundino 120 and has a ratio 100:1.So I put values,1/8,10 and 100 and gave me 555,5555556.It runs smoothly and homes.My only issue is that it cannot give full 360 rotation when I give g coded G0A360.Any help manaybe setting in General config and rotational settings?Thanks
Alexis Damianidis Thanks for the compliment. In General Configuration, make sure "A-Axis is Angular" is checked, and that everything under "Rotational" is un-checked. From a zeroed dro, try the G0A360. If it doesn't go the 360, try "444.4444444" as steps per degree... which is "1/8,8,100" in the chart.
Υou are awesome bro,360 degrees dead center.It seems unchecking everything under 'rotational'' was the problem.Keep making videos I like your attitude and spirit in your videos....;)
+ToniczTutoriales The rotation radius is half the diameter of the tool path location on the part being engraved. If you are engraving on a 10mm diameter, the rotation radius is 5mm.
+ToniczTutoriales Oh wow, I'm not sure. I don't have any problems including a decimal. It's ok to not include a decimal number. The rotation radius number seems only to effect the tool path display and feed rate calculation. Neither need to be that accurate. You should be fine with a whole number. Still it is weird that it won't take the decimal.

howdy again so would u say i need a program like F engrave to work on round pieces like pool cues? or can i do it by tweaking settings?
I use both F-Engrave and Gcode-Ripper. For me, they work great.

Hi! I follow all the steps in the video but my motor lost position every now and then for example after 10 cycles of work the actual position it's moved 0.7mm from the original position. Do you know why is this happening? Greetings
Try slowing acceleration a bit for the rotary, in motor tuning. See if that makes any difference.
I'll try thatthanks for answer!
3:24 , its fine if u put rotary parallel to Y axis BUT 180 deg. rotated, i dont see change rotating
If you need, you can change the direction pin of the axis.
Hi, is it the same way with AC Servo?
Not exactly sure since I haven't messed with them.

Hi Charlie when checking GOA360 in MDI should the A axis rotate by itself I have tried this but it does not rotate

It should, unless the DRO is already at 360 in G90 mode. Can you move the rotary axis via MPG mode (tab key)? Did you watch this whole video going through all the rotary settings?
yes I did, will try the tab key in MPG, A axis was at zero in read out have got everything else ok I think cheers Rocky

How many rotations of the motor does it take to turn the rotary chuck 360deg?
