Hi , good video , I have one question for you … on my cnc I’m necessity to exchange y with z and reverse direction , I’m sure is possible it with remove the wire , but I’m necessity make it on software , same system of parallel port ( exchange number of pin of step and dir ) please help me ….. I’m necessity but use my cnc for cut a foam with hot wire and z change on y , the foam is vertical on surface and wire is parallel at y axis and applied on z axis …
if you watch all the videos its in there somewhere, but in prots and pins active low reverses travel... on the nvem I believe the easiest way to change x and y is through wiring
Hi DZ Mech Great tutorials . I use mine to run a cnc plasma cutter. Trouble is I want to run a Torch height controller Would you know if NvemV2 board is able to do this. Any info would be a great help
Not sure on that one! I was planning on designing and making a plasma and waterjet. never got around to it, personal and financial problems popped up that's life! maybe some day! :) if you figure it out please share you learnings :) Help the other guys...
Hello !!! Please show how to connect and control PWM I need PWM to control the laser power I don't know how to set pin or port numbers in mach3. Everything else works
DZ I am surprised that your motor travel distance "steps per" isnt a round number to "say" a nearest 100 - mine has never calculated out to really odd single digits...ie 33
Hello, I have the problem that in the Motor Tuning and Setup window my X &Y Axis are always have the value between 0-1. Its doesn't scale when I change when I change the value of the Velocity for example. I can't even change the Velocity it always jumps back to 0. Can you help me? Thank you!
Make sure you have the proper version of Mach3 I had loads of issues with the newest version Newfangled even said somewhere they'll tell you to revert to a certain before troubleshooting, i believe. also, make sure it's licensed not sure if this will help.
@@trondwell13oh and backup your xml config. I'm still trying to figure out the pwm spindle output, it's not going well (haha) but maybe I'm asking to much.
Hello, I am thinking of using a DC Motor Spindle. I want to use NVBDL+ as the Spindle Driver and NVEM as the CNC Breakout Board. I want to control the Spindle Speed with PWM. What is the appropriate connection between NVBDL+ and NVEM?
Thank you for your videos they have been very helpful. I have a quick question. Can i add a J tech photonics laser to the controller board? I use a router on my CNC so my spindle pins are all free. Hope you can help.
Hey Sarah Thank you! You can use the spindle outputs 1 or 2 for a laser. There is a pin marked GND to the left of the Vso pin. That's the outputs input/feed for the spindle outputs. Most lasers have the power supply connection and an i/o connection, so the laser power supply feed would be left alone in this instance, and you would have to run the ground from the laser i/o trigger wires through the nvem and back to your laser, essentially making your nvem a ground side switch for your J tech Module. Which model are you getting and is there literature on it? After that if your are using mach 3 for the laser its super weird and you'll have to play with settings and delay times to get it to turn on and off without continuously burning through the work piece. There's a differrent post processor for the laser if you're using mach 3.
@@DZMech may i ask you some help pls, im up to set the similar setup. bought laser from laser tree on aliexpress. it has +12v, GND and PWM 0/5 - 12V, 0-1kHz, how should i wire it up to Nvem ?
@@Marcmk1 this may be an issue mach doesn't change the pwn frequency very well. on the spindle in/out you have to splice the ground from power in and feed the gnd on the spindle bar. same as the output bar, Nvem doesn't feed those internally (poor design) I ended up finding a work around with a pwm frequency generator. but I speced & ordered it for my application, 5 v output pwm. not sure if this helps
@@DZMech hoiw can i contact you please? i would like to send you a picture of the wiring setup to ensure i understand your advise right before powering up. shall i give you my email or you want to share yours? much much appreciated mate
DZ plz can you help me, Do you have an email where I can contact you, to be able to give you the details of what I need your help with, I am building a small cnc lathe, but I cannot make the motors work correctly, since they lose steps and move very irregularly, I have motors nema 23 drivers are DM542T and the board is a NVCM2.1
I use dm542t on most of my builds. Look up the Nema 23 motor datasheet and on the back of the motor there should be an amps rating. makes sure you are within specifications below peak amps. setup your motor driver (power off) with the dip switches, to the proper amps and resolution. (I used 4000 for the resolution on my mill and the new lathe conversion I may go with a lower resolution 4000 is too fast) after all that is ok... go into motor tuning and slow everything down. Accel and Velocity then recalibrate all the axis' after. I believe loosing steps could be from going too fast in the software or a mechanical issue so also check all you motor couplers ballnuts and end bearings etc. email is up there if you want to brainstorm... :) If you find an issue please post here maybe it will help someone down the road :)Good luck!
I think that maybe a great question for Newfangled solutions and Novosun. My thoughts on it are originally when Mach 3 came out it was meant for a printer port style connection which may have ran at a much lower frequency the ethernet. then came ethernet smooth steppers ethernet has a broader range of frequency speeds. But thats just my theory nothing more than a theory. Novosun may have just printed on the to advertise that it can... use up 200 khz but you'd need software to hit those speeds? Which Mach 3 does not.
I think that Mach3 dont send pulses step/dir in Khz. to the ethernet, I think Mach3 send data of pulses speed/dir in numeric and code way, then the NVEM with this data convert it and send pulses step/dir at 200 Khz. , with more capability than LPT port due to have a microcontroller dedicated in the board.
Another good material. I bought NVEM. I will follow the instructions from the next films

Have you heard much on the plug in wanting a bin file? Can’t seem to get past this not finding a bin update from the manufacturer
haven't heard anything from the vendor or manufacturer sorry

Would you know if NvemV2 board is able to do this. Any info would be a great help

Hello !!!
Please show how to connect and control PWM
I need PWM to control the laser power
I don't know how to set pin or port numbers in mach3.
Everything else works
Mine don´t let me change velocity. The value is allways 0. Any idea?
This only happens with nvem dll
DZ I am surprised that your motor travel distance "steps per" isnt a round number to "say" a nearest 100 - mine has never calculated out to really odd single digits...ie 33
Hey Dan, that was just to get the motors moving the steps change as you may know already after calibration.
I bought NVEM I have problem, the step jog not move

The NVEM can reach 200kHz but Mach3 can reach 100khz.
How is it possible to reach more than 100kHz on Mach3?
why?
