Recommended Posts

Posted · Cura beta 4.1 bondtech um3

hello in the new update of cure in advanced profile system I see that I can modify parameters of the printers as the steps of the engines among others, with this method could mount a kit bondtech in my um3 adjusting the steps from cure?  Thank you

I don't see this feature in Cura 4.0.  The most it can do is add some gcode but you can't update steps/mm in UM3 with just a gcode (you can on UM2).  You should know however that bondtech has a new installation procedure that runs a program that updates the steps/mm for you.  This is for people not comfortable with linux (UM3 runs linux).

 

I found that the feeders are so powerful on the UM3 that there is no need for the bondtech.  Unless you are printing CF.  The UM3 gears aren't hardened enough for carbon fill filament but the bondtech gears are.

I'm printing colorfabb xt cf20 carbon.  I appeared in beta 4.1 at the end of the whole in the profile setting options. Where can I see the new form of bondtech for ultimaker 3 without touching Linux?  thank you

I run a pair of Bondtech QR’s on my Ultimaker S5. I added

 

M92 E492.45 ; set E-steps to 492.45

M500 ; saves value

 

to the start G-code in the printer’s machine settings. It isn’t elegant, but it works. The only time I have to send the gcode manually to the printer is when I restart and want to do an xy calibration. (Getting the E-steps right doesn’t matter for filament changes.) Otherwise, the E-step values are stored on the printer. 

 

I did have to disable the flow sensors in the printer settings, but I’m almost done prototyping a housing that adds the UM S5 flow sensor hardware to the Bondtech QR’s.

What was the reason to change the S5 feeders for the QRs? 

Before S5 I can understand it, but in my opinion, the S5 feeders are great and I cannot see any advantages currently with the QRs?

(1) I print mainly carbon- and glass-fiber reinforced materials. 

(2) with the Bondtech, I can print Ninjaflex and other flexible filaments at reasonable speeds. 

 

And even with the improvements to the Ultimaker extruders, the Bondtech QRs are still much better.

The machine settings for Steps per Millimetre are normally not visible (only because you installed a plug-in that makes machine settings visible).

 

They are not used currently by CuraEngine but only by the X3GWriter plug-in to convert to X3G properly. However in the future we might use them to improve aliasing when rounding to steps or halfsteps.
