Bigtreetech Scylla V1 firmware installation.

[Stevo]

I have a figure of 401.6669905 steps per unit for my steppers in the UC CNC screen grabs i took would that still stand for this build the figure is the same for all three axis

There are trips on the ends of all three axis's but wired as a ring so if any of them get tripped the machine stops. Will need to rewire these individually on the Scylla to work as homing limits and maximum travel limits.

Can do away with these drivers presume the four wires to the right on the driver will go into the connectors on the Scylla need to check how I have wired the motors as there are eight wires paired down to 4 could be series or parallel configuration ?

So rightly or wrongly I thought using the rep rap configuration tool would help me sort out the steps per mm for the three axis's. I also added an axis to shadow the existing Y axis. You can view the G-Code this particular section creates.  I'm not convinced that 640 steps per mm is correct for 1.8 degree motors on a 5mm pitch leadscrew. ( both the 16mm and 20mm ballscrew have 5mm pitch ) PFarm could you clarify if i have done this correct please.

Not sure if the shadow y axis will also abide by the original y axis endstops ?

• Thanks for the photo the VFD is the same as mine, the A/B wires are the only wires you'll need from the external stepper drivers.
• The steps per mm value we'll input into the firmware do you have the micro-step setting 16 or 32?
• Is there a single microswitch per motor axis?
• You'll still need the 24V power supply plus your 48V. 24V will be wired to the V-MOS and V-MCU the 48V. to the V-Motor. You can upload the latest firmware with Millenium OS. Once uploaded I'd suggest updating them to RRF 3.6 and Millennium 0.50 I'll guide you through that both are still in beta but Nine Miles and I have been using it with no issue
•  Do you have the work area dimensions we'll need to input that?

Before disconnecting your setup, I suggest taking a photo of all the firmware setup windows. It can be useful to program Scylla. If you have a backup of your G files that would be useful as well.

These are the setup pages that are used on the UC CNC controller that the machine was / is running at present. The 400 figure for steps per unit on the three axis's is purely a UC CNC thing!

• Thanks for the photo the VFD is the same as mine,  the A/B wires are the only wires you'll need from the external stepper drivers. 
• The steps per mm value we'll input into the firmware  do you have the micro-step setting 16 or 32? ( not sure is best for this )
• Is there a single microswitch per axis? (There is one of those micro switches at either end of the travel for all 3 axis's)
• You'll still need the 24V power supply plus your 48V. 24V will be wired to the V-MOS and V-MCU the 48V. to the V-Motor. ( okay no problem will retain that when it arrives. ) You can upload firmware with Millenium OS ( will need a nudge how that works / integrates?)
•  Do you have the work area dimensions we'll need to input that? ( I have added rough sizes of travel in the maximum travel in the above 900 on X 1200 on Y and 250 on Z

This M31 Macro is one that I had to use to over right the original within the settings to get the cutter height setting tool to work and to adjust the figures to calibrate.

Many thanks to the original writer of this script has been useful.

Instructions to install RRF and Millennium onto the Scylla RRF install.  The instruction is the same as uploading the Mellow CDY V3. Here is the link for the Scylla firmware.

In regards to the micro switches will I need to wire up all three contacts for each of the six ?

No you won't, preferably wired to the normally closed contact of the switch.

Have already loaded that onto the board as you mentioned earlier and have wireless connectivity from my laptop to the board with the Dashboard

So to clarify the current is broken when tripped correct ?

[PFarm]

Correct! No voltage is sent to the microswitch only the Ground and Signal pin are used to confirm activation.

Do you have a din rail handy? Can be used to mount the Scylla and the contactor to your setup.

I do not but I am going to see what space it takes up and get a project box to fit it all in when its up and running. ( minus the VFD )

What voltage is your water pump? Do you run any fans in your setup?
