  • 6 Axis CNC MACH3 Engraving Machine Interface Breakout Board USB PWM Spindle With ASKPOWER A131 Series

    Hi the image is bit small to see what is what but...if i read right : Where to connect PC5V and PWM...do not connect anywhere PWM is there in case you will use that pin for reading the pwm signal or as normal output pin. But you use the 0-10V out which uses pwm pin signal to convert ist so do not connect anything. PC5V it is just 5V from your usb supply to board (i think).The other cable from inverter where you wrote where to connect... i dont see at all where it is connected on the inverter so i cant help. but the other 4 cables seem to be all you need as on is the 0-10V and ground and the other is spindle on/off signal probably as as connection trough that relay. so that is sufficient.About the powersupplies: Yes seems you need two. becasue your drivers on A,B needs 30V. and board sup...

For the drivers there you need proper powersupply with sufficint ability to supply current. it is mix of drivers one 3x 24-50V 4.5A and other 2x 3.5A @30V(but that driver have probably bigger voltage range if you had trouble to find 30V exactly look at the driver specs.) so 30V is good for voltage range and curent is 3x4.5+2x3.5 = 20,5A minimum but go for higher current to be on a safe side, so you know powersupply can supply curent if driver needs it. Or you can power every driver separately, or group of drivers that is also an option."can i utilize the powersupply i picked from you?" i assume this message was originaly for someone else :DBR

    Hmm, maybe the board itself have some problem, there are probably more manufacturers making the same board, that could be an issue. but as i said before. there surely is compensation somewhere for this in mach (i know in mach it couldnt result in higher voltage but could in different dutycycle so you get correct speeds but the spindle will not go let say over 350rpm even capable of 400rpm, to be honest i never used more than 300rpm anyway) or the inverter have some compensation. these compensatiosn are there for this specific case, i know it does look it is not perfect but... you can set it close enough. or you have an option to try set your inverter with Modbus if the inverter supports it... that is by far the best and safest option for controllling the inverter anyway. it kind of happ...

  • 6 Axis CNC MACH3 Engraving Machine Interface Breakout Board USB PWM Spindle With ASKPOWER A131 Series

    i think your setup is fine. the pwm frequency doesnt affect the duty cycle so when the pwm is fully ON it is basicaly the same as 5v signal and should result in 10V output. I am not sure but mach3 probably have some setting for max pwm frequency something pointing to the fact that for example 400Hz is limit for given spindle, i am not sure at the mmnt i was making some setting for this, but maybe that was on the inverter.

    On this board(the one i made tutorial for) the answer would be connect the pwm input of your laser to Pin1. and also you need to connect some ground conection most probably your laser module have 2 wire input for pwm... so PWM to pin1 and ground to ground. About the parallel port signal... yeah that should work too but once i measured output voltage of my parallel port and it was around 3.5 volts which should be fine for ttl electronics but you never know... also the breakboard isolates the connections of parallel port so it is safer for the pc in case something goes wrong. so leave the parallel port out i would say. (well unless the base frequency for the pwm for the laser is so high that the optoisolators in the breakboard arnt quick enough but... that shouldnt happend)also you should...

(well unless the base frequency for the pwm for the laser is so high that the optoisolators in the breakboard arnt quick enough but... that shouldnt happend)also you should disable the pin allowing 0-10V generation (there is jumper for this on the board step2 of my tutorial) as that might use some capacitor and already smooth the 5V signal on P1 which is not something you want. in worst case the pwm will not work and your laser will be fully on or fully off... that the worst what can happend if you conect it to P1 as the voltages there are 0-5V. unless you switch the ground and PWM signal which might result in -5V which could damage something but i am only guessing as i dont know your whole setup.also if you connect on your laser module the pwm input to ground (basicaly connect the two connections for pwm) the laser should turn off... just a test that the input even works...good luck

    Thats realy nice, but no thanks :). let me know if you got it all working.BRVlado

    So your setup goes like this (attached image)the + - connections are to powersupply that depends on your laser, might be something like 12V 2-3A. Also I am not sure if you will be able do grayscale... it always is kind of on off.... changing the intensity of laser will mostly change size of burned place... and usualy you will be glad it burns the material with the intensity you need which can be set also by current if you have variable powersupply.Just a thought, you can set the laser same way as your pen... i mean set it only to on/off full pwm looks like 5v and no pwm looks like 0V anyway....so PWM contact to where you had your pin for pen and you are burning....also the on/off mode can be set on Pin1 you dont need to even change the hardware setup.

Pin1 is dedicated to pwm ... i think only because there is quicker optoisolation to handle the pwm base frequency.and lastly the speed of your machine also affects the laser intensity so you could have non variable powersupply having laser on full strength and speed will afect the intensity of the burn.BR

    Pin1 doesnt output 0-10V you only need the pin leave free so you are not sending there anything else then PWM. ... well you could attach osciloscope to see the frerequency sent from mach. but if you look at the schematics there is pin called 0-10V output. the board uses frequency on pin1 and translates it to 0-10V on this output... so just measure this output for 0-10V

    I dont think the board have directly associated outputs. It is, for example P3 on the board represents pin3 on paralel port so in mach3 you set pin3 in ports and setings to whatever purpose you need and that will be behaviour of P3 on the board. same goes for P4, P5 atc...

    just added. you will find it in one of the comment

    I have 3d model but i will keep that, as that was to help me to decide about thinks, not much about corect dimensions. I have searched for known components so here are the racks, pinions, drivers, motors. the rest was second hand or from local shops so i dont have any links for that. The Z axis screw as i recall is 2cm wide and z rails where only 15mm wide not 20cm as the rest but all that was scond hand thats why i made the nut holder atc... you will need shielded cables, energy chains limitswitches but for all that i just choosed what found first but the component list holds the most important parts on which i spent lot of time reasoning why these.X axis:http://www.cnc-discount.de/epages/62924595.sf/en_GB/?ObjectPath=/Shops/62924595/Products/%22O20%20%201600%22http://www.shop.cncdriv...

    Thanks. The step have in its name (avoid this) it is just showing my path and this welded support was mystake. There is picture with support, simple screwed together square pipes example. welding bents the metal... hard to avoid for me or any beginner i suppose. You could avoid the support completly if you had flat enough surface or just use the 2 square pipes you see on top of the welded support.. any simple support resulting in 4 legs which you could adjust somehow to make the bed leveled would do. I had friend with mechanical degree sugesting the weld is important. from my experince now it wasnt. 8mm screw where more than enough in the rest of the construction so it would be fine for the support too.

    You basicaly described the proces how i was trying to do it. I touched the oposite corners atc.. but still the owerhanging top parts of the support where pulled down. It was annoying thats why i dont recomend it. We are talking 1mm per roughly 40cm. But if you know how to make the weld properly then sure, welded construction counts like one piece. So better then more screwed together.

    :D i was glad to finish thisone...but i suppose we could have chat about it if u are serious.

    It is shipping container, but yeah as i am checking the machine it is 2m wide :D i need to change this in name. the woking area is x1430, y2680. cost was around 3000e. but not sure exactly as i bought many parts and i lost track. I looked into belt and pinion but belts are stretchy and ive seen big machines with belts and i just coulnt imagine 3m belt to move 50kg (or more) bridge without stretching. Yeah even simple aluminum or better dural square tubes would be good choice.

    In short; it shouldn't be a problem.You need to pick motor driver as the board controls the driver and driver controls motor. The board sends direction and step pulses to driver (i would say this is standard for all driver boards), so you have two connections there. And motors are 4 cables bipolar and 8 cables unipolar both can be connected in bipolar setup. Just check the driver, it should have 4 connection A+ A- and B+ B- for the two motor coils.

    I will need to test this to be 100% sure abut why i set it, but you are right i didnt needed the output1 as the pwm signal is set in Config / Ports&pins / motor outputs / Spindle.

    CNC Plasma Table

    Very interesting. I am really starting to wonder what the plasma i ordered will do :D. I really hope it is ok to post a link so you can have a look. their HF plasmas are 3phase. I have single phase and it is touch start and it is Pilot Arc. http://www.telwin.com/webtelwin/site.nsf/webindex?... So what you recon? without HF what would be the distance it would be able to strike proper arc? In my view you have high voltage charged electrode which ionizes air so creating conductive path for the arc thats why i thought 5mm isnt totally impossible, but yeah... maybe not too real either. I will share my experience once ill try the machine out. thanks for your answers

    SiThanks for the replay and important info. I for example didnt realized about RFI. And i should have mention that even the plasma i bought is "touch start" it does have pilot arc so it will cut mesh or rusty material. (not sure if i can post here link to the shop so i rather didnt) Basically from my research HF is to create the initial spark, touch cant do that. You need to (touch) or in case of my machine according to manufacturer be less than 5mm from material. So if i understand all i am risking here is that the initial start will not work? Also cutting on pilot arc doesnt really make a sense to me as it wouldn't cut the material with same power so you might not cut trough or cut will be uneven. So i see little difference between not cut material or cut badly (on pilot arc...

Bare in mind I dont own yet any plasma so; no experience :D. Thanks for all infoThanksVlad

    HiIn text is written: The cutter must have 'HF Start'. I wonder why is that? I was ordering plasma for my machine recently and it is not HF and according to manufacturer the torch just needs to be close enough and the arch will strike, similar to use with roller guide wheel. So why it wouldn't work on your machine and why it is must have? the HF creates strong interference with electronics if cheap machine bought, so bigger problem would be using HF.
