==Update: (10/21/2022)==
The LongMill has been installed on the shelf in the "Large Projects" area, along side of the MiniCNC.
===Machine Overview===
===Machine Overview===
Bed size: 250mm x 340mm (10"x 13")
This is a SIENCI (pronounced "CNC") Labs LongMill ( See https://sienci.com/product/longmill/ ) with the short rails.  The web page says it is 12"x12" but in fact it is more like 10"x13".


Spindle:Makita Trim Router (Variable Speed)
The controller is an Arduino running GRBL.  <br />There is a ton of valuable reference material on their "Resources" website.  See -> https://resources.sienci.com/view/lm-welcome/


Automatic tool changer: No
For technical Details see https://resources.sienci.com/view/lm-longboard-documentation/


File units: Default units are Metric.   
'''Bed size''': 250mm x 340mm (10"x 13").  The Z travel is 105mm.  The clearance below the gantry is also about 105mm so this is the thickest material that could be mounted, although the router can be adjusted higher if the material has the right shape to clear the gantry. There is about a 60mm offset from the gantry to the router bit (in the Y axis) that could be used for taller pieces.


File type accepted: .tap, .gcode, .txt
'''Spindle''': Makita Trim Router Model RT0701C  ( https://www.makitatools.com/products/details/RT0701C). The Makita Router has a 1/4" collet, and a also a 1/8" collet insert. Manually controlled, this router has variable speed spindle from 10,000 to 30,000 RPM.  It is manually controlled (Not controlled in software).  There is a collection of bits in the red toolbox under the CNC.  


Machine control software suite: GRBL on a SIENCI Milling Labs Controller.  The controller is also connected to a RaspBerry PI which has Universal G-Code Sender (UGCS) as well as bCNC installed.  
Currently, the Spindle power is not controlled by the CNC Controller and must be turned On/Off manually.  This is on the list of improvements.  


Will do 3 axis moves?:Yes
'''Machine Control:''' GRBL on a SIENCI Milling Labs LONGBOARD Controller.   


Hold down method: Screws, nails, clamps(must make these).  
'''User Interface:''' The Raspberry PI that was originally installed has been replaced with a faster and more robust "nanoPC" (model nT-A3800) connected to the Controller via USB.  It has [https://resources.sienci.com/view/gs-installation/ GSender], [https://winder.github.io/ugs_website/ Universal G-Code Sender (UGCS)]as well as [https://github.com/vlachoudis/bCNC bCNC] installed.


Dust collection?: Yes, requires a shopVac.
'''PC Login''': The Debian logon on is automatic on startup, so you do not need to log on. But if you need it for any reason, it is protospace/protospace.
Probing: plate style. Plate is 10mm thick as well as X and Y 10mm offset.  


Suitable stock materials: Wood, plastics, foams, other.
'''Hold down method''': Screws, nails, clamps(must make these).  


Unsuitable stock materials: '''Zero''' metal, metal alloy, or metal composites are to be cut on this machine
Note that the base plate mounting board is MDF but '''IS NOT A SACRIFICIAL BOARD'''.  The mounting board has threaded inserts on a 10cm x 10cm grid.  You can supply your own hold down board with whatever system you wish.  Simply drill holes in your board so that you can mount it to these threaded inserts.  The threaded inserts are 10x24.  There are a sample supply of different length screws for you to use.   


===Machine history===
'''Dust collection?''': Yes, requires a ShopVac.
The LongMill CNC was donated by Peter Careless.  He built the stands as well as the shelf and power bars for the electronics.   
 
'''Probing''': plate style. Plate is 15mm thick as well as X and Y 10mm offset.
 
'''Suitable stock materials''': Wood, plastics, foams, other.
 
'''Unsuitable stock materials''': Zero metal, metal alloy, or metal composites are to be cut on this.  If the CNC machine was on the rolling cart, it possibly could be moved outside to do some aluminum milling, but for now don't do it.

Update: (10/21/2022)

The LongMill has been installed on the shelf in the "Large Projects" area, along side of the MiniCNC.

Machine Overview

This is a SIENCI (pronounced "CNC") Labs LongMill ( See https://sienci.com/product/longmill/ ) with the short rails. The web page says it is 12"x12" but in fact it is more like 10"x13".

The controller is an Arduino running GRBL.
There is a ton of valuable reference material on their "Resources" website. See -> https://resources.sienci.com/view/lm-welcome/

For technical Details see https://resources.sienci.com/view/lm-longboard-documentation/

Bed size: 250mm x 340mm (10"x 13"). The Z travel is 105mm. The clearance below the gantry is also about 105mm so this is the thickest material that could be mounted, although the router can be adjusted higher if the material has the right shape to clear the gantry. There is about a 60mm offset from the gantry to the router bit (in the Y axis) that could be used for taller pieces.

Manually controlled, this router has variable speed spindle from 10,000 to 30,000 RPM. It is manually controlled (Not controlled in software). There is a collection of bits in the red toolbox under the CNC.

Currently, the Spindle power is not controlled by the CNC Controller and must be turned On/Off manually. This is on the list of improvements.

Machine Control: GRBL on a SIENCI Milling Labs LONGBOARD Controller.

User Interface: The Raspberry PI that was originally installed has been replaced with a faster and more robust "nanoPC" (model nT-A3800) connected to the Controller via USB. It has GSender, Universal G-Code Sender (UGCS)as well as bCNC installed.

Instructions and Training

How to turn on the machine

The main power is turned on by turning on the common power bar for the shelf. This also turns on the lights as well as power for the MiniCNC

. Main Power Bar Switch LongMill power bar

There are 2 power switches to be turned on (not counting the monitor).

  • The nanoPC has it's own power supply plugged into the power bar. There is a power switch on the front of the PC.
  • The SCENCI Longboard has a power switch.
  • And finally, when you want to start the Router, you also need to turn on the switch on the router. (Note: that this may be put on a more convenient switch and even maybe software control in the future. )


LongMill Controller power RaspberryPi Power Makita Router Switches

Once the power is turned on, you will see the Debian Desktop. You now need to launch one of the programs that will talk to the Controller.

UGCS is written in Java, and bCNC is a Python program. I refer bCNC and will document that here.

How to Jog and position the Router:

The LongMill does not have travel switches. ( https://resources.sienci.com/view/lm-adding-limit-switches/ ) Instead, you manually jog the router to a position that you wish to use as a starting point, and then zero the XYZ references.

There is also a touch plate to assist in getting precise Z (as well as X and Y) references for you particular material.

Fusion 360 Notes and Tweaks

The SIENCI LongMill is not currently listed in the machine library of Fusion 360. You can however import a definition using a file created by one of the members of a LongMill facebook page.

Follow these instructions:

Also, one note on Fusion 360 on their Resources website:

**To avoid potential issues with Fusion 360, we also recommend you make the following checks to your post-processor:

  • G28 Safe Retracts set as “Clearance Height”
  • Output M6 set as “No”
  • Output Tool Number set as “No”

Reference links

Planned Updates

  • Add Power Switch for Router Power
  • Add E-Stop switch
  • Add e-relay for Router Power (Power control in G-Code)
  • Add Travel Switches.
