  1. Re: From NEMA 27 to NEMA 34 and voltage type selection

    Again great content!



    You direct short them or have a diode per driver signal?
    Also there's any advantage of having the controller enabling the servo opposed to permanently enabled? If yes...
  2. Re: From NEMA 27 to NEMA 34 and voltage type selection

    ASD-B2-0421-B + ECMA-C20604RS



    Is not possible short GND to one of that inputs in CN1 to always have it active by default (Manual shows DI1, so DI1-COM-)? Or i really need to tie it to the...
  3. Re: From NEMA 27 to NEMA 34 and voltage type selection

    Ok it seens i need to activate servo first, i use P02-30 set to 1 and it works, but as soon i restart power i need to do it again...
    Which pin on CN1 i must short with to always activate servo?...
  4. Re: From NEMA 27 to NEMA 34 and voltage type selection

    Got my servo some days ago.
    Have finished the instalation today, but when i try to jog axis nothing happen.

    I just changed these parameters on driver by hand since i don't have cable yet:

  5. Re: CNC Router best way to drill 300 holes on 6082-T6 95HB

    Thank you for suggestions.
    If i go endmill helical a 4mm endmill is ok or need lower?
  6. Re: CNC Router best way to drill 300 holes on 6082-T6 95HB

    I have compressed air + distilled water mist as coolant but i plan to do it dry if possible.
    That's why i need to go slower. Will slower speeds be harmful for the drill?
    On past job i drilled 8...
  7. CNC Router best way to drill 300 holes on 6082-T6 95HB

    I have a all steel 6090 cnc router, i need do about 300 holes on a 6082-t6 20mm thick sheet.
    I already order some carbide drills but calculator is giving high feeds which is not good for my machine,...
  8. Re: Improving my waste board stability and rigidity for harder cuts

    Well you have one solution, do a machine of small size and your wish comes true ^^



    My machine is heavy due to steel content, is +/- 400kg as it is now, i can't move, shake or lift by my hand....
  9. Re: Improving my waste board stability and rigidity for harder cuts

    Yeah that's almost 9 to 10x my machine, it could cost you some big money but now you are enjoying more and maybe results in better work and pieces, and maybe it already pay off... So is not necessary...
  10. Re: Improving my waste board stability and rigidity for harder cuts

    I design the cap hole to be 10mm deep, that way it will accept both M8 button and cap heads with a margin of +/- 2mm for cap heads, so if i go 15mm, will have 5mm remaining to support the cap,...
  11. Re: Improving my waste board stability and rigidity for harder cuts

    Thank you for explain.
    That case i think i will go with my 1) & 2) Ideia, that way i can hard clamp stuff without the deformation from screw and i guess the aluminium sheet will last "forever"....
  12. Re: Improving my waste board stability and rigidity for harder cuts

    The kind of nuts i'm using are the following:

  13. Re: Improving my waste board stability and rigidity for harder cuts

    Price is not a problem, sheets are cheap here. Due i want rigidity i think i will go for it.
    Now what thickness should i go? I can choose from 10, 12, 15, 20, 25, etc... What thread depth i need to...
  14. Improving my waste board stability and rigidity for harder cuts

    I have an all steel CNC router, the table is a solid steel sheet, in top of that i made a waste board from a particle board with M8 inserts under arranged in a matrix

  15. Short earth with 24Vss(gnd) to have signal on endmill can be harmful?

    I have an all steel CNC router that chassi is connected to mains Earth, so all body is earthed, without earthing and only when spindle is rotating chassis have about 240VAC but very low current as it...
  16. Dust Shoe hose angle (45º vs 90º) for best Airflow?

  17. Re: From NEMA 27 to NEMA 34 and voltage type selection

    I'm currently at 600mm/s2 and 2000mm/m with the steppers.
    I'm not aware of my machine weight, but to lift it it required 4 man, and that was already painfull and dangerous to move and lift. So i...
  18. Re: From NEMA 27 to NEMA 34 and voltage type selection

    Servo is on the way :D

    As the ABXX-E have no differential pair output, does it worth to buy a module (https://www.aliexpress.com/item/33013825383.html) and use? It have any other benefit than...
  19. Re: From NEMA 27 to NEMA 34 and voltage type selection

    Now with the math fixed it make a lot more sense :)
    Thank you for such detailed explanation.

    I will start upgrade axis per axis and see how this turn, not sure if i will benefit with a servo on...
  20. Re: From NEMA 27 to NEMA 34 and voltage type selection

    Only a man who loves this can write such explanation :)

    There are a few things i can't sort out and get confused, such as:



    Where's the 10000 value comes from? Shouldn't be 12500?
  21. Re: From NEMA 27 to NEMA 34 and voltage type selection

    All my steppers and mounts are NEMA23, sorry for confusion, my bad, sometimes i type 27 instead of 23 don't know why... So where i said 27 should be 23.



    Yes that the easiest axis (Y) to...
  22. Re: From NEMA 27 to NEMA 34 and voltage type selection

    After order some parts i just notice that these Delta servos use NEMA24 frame holes, it dismatch my nema23 holes by just 2 to 3mm. That mean i can't directly mount. Also i can't use an adapter...
  23. Re: Nema 34 12.0 Nm(1699.68oz.in) or 8.25 Nm(1168.53 oz.in)????

  24. Re: From NEMA 27 to NEMA 34 and voltage type selection

    That way, there are two possible options, using external 24V psu (the same from AXBB-E) like show on sticker, or using delta power supply internal 24v and merge every GND. Which is the safest? As GND...
  25. Re: From NEMA 27 to NEMA 34 and voltage type selection

    I think i found the difference at least on driver... The Delta logo is missing, ground screws are not green, ltp port not covered. It seens a clone of delta and not the original? I'm split, both have...
  26. Re: From NEMA 27 to NEMA 34 and voltage type selection

    After doing some math, stepper + driver would be arround 180€ plus any tax if it stop at customs. And not including the power supply,thats maybe 100€ to 150€. It will end at same cost of a china...
  27. Re: From NEMA 27 to NEMA 34 and voltage type selection

    As EM882S alternative can i use: DM2280A 110-230VAC input stepper drive - CNCdrive - webshop so i can power it with 220VAC directly instead of buy Power supply?

    The stepper i can find it cheap...

  29. Re: Machine home altered after play with toolpath viewer while cutting

    This is getting interesting, good information here.

    I will also upgrade steppers and...
