retrofit cnc press brake with Dynomotion

[Westjava]

Dear everyone,
I'm new here. I want to ask, has anyone ever retrofit a CNC controller press brake machine with KFLOP and KANALOG of Dynomotion?

Does this run with G code?

[TomKerekes]

Yes

[Westjava]

thank you, my leader is currently purchasing canals, kflop and konect. is there a sample g code for the press brake, so that later I can develop it when my order arrives?

Hi irmad,

You would need to be more specific what you need to do. GCode for a press brake is usually fairly simple. Move down to press, dwell then raise the press. Something like:

G21 (mm mode)
G 1Z-100 F100 (Move down at 100mm/minute)
G4 P2 (dwell 2 seconds)
G1 Z0 F200 (Move back up at 200mm/minute)
M30 (end)

[Westjava]

got excited, wanted to start to retrofit.
Sir, I contacted sales @ dynomotion many times. but there is no answer. because my leader is willing to buy.

G0 z1000
G21 (mm mode)
G1 Z500 F100 (Move down at 100mm/minute)
G1 Z250 F50 (Move slow down at 50mm/minute)
G4 P2 (dwell 2 seconds)
G1 Z1000 F200 (Move back up at 200mm/minute)
M30 (end)

please, give me advice for the code I made above. is there something wrong.
and how to add additional code for swith / pedal. because I want this code to run when I step on the pedal. there are 2 pedals in my engine, for up and down.
I deliberately wrote z1000, because I wanted to start from the top position, and as Top Dead / Homing.

Hi irmad,

What is the problem? What happens?

One issue I see is you do a G0 Z1000 before setting mm. So that might be inches instead depending on the mode.

and how to add additional code for swith / pedal. because I want this code to run when I step on the pedal. there are 2 pedals in my engine, for up and down.

The code moves up, then down, then up. Why would you want an up and down pedal? Please be more specific on what you want to do.

oh ... my god, i just got it now. meaning z0 is starting from the top, or the beginning of the RAM position is above, and must write G21 first. I'm sorry sir, because I don't understand the article about the g code that I read, they write x0 y0 x0 is in the middle / homing, if you want to go up 100mm, the number becomes z100 (that's my understanding).
while for the pedal, if I choose manually, I use 2 pedals, the right pedal to go down and the left pedal to go up. if I choose auto, I only use 1 right pedal, the ram will go down fast, then go down slowly, then silence 2 seconds, then go back to homing / TDC, and the left pedal to cancel so the ram returns up / homing.
