Rigidbot Big Buildplate Counterweight
Description
You Wouldn'T Run A Single Piston Internal Combustion Engine Without A Counterweight As It Would Shake Itself Apart. This Is The Theory Behind Adding A Counterweight To My Y-Axis And Now I Have Finally Put It Into Practice. First I Lightened My Y-Axis Carriage And Build Plate By Drilling Lots Of Holes. I Then Added A Set Of Linear Rails And A Tray To Hold Two Lead Counterweights To Offset The 1850 Grams Of Moving Mass That Makes Up My Y-Axis. Note The 6X20Mm Steel Bar Attached To The Bottom Of The Counterweight Tray Which Is Mainly For Rigidity. I Increased The Stepper Motor Size To 1.8A With A 4.8Kg.Cm Holding Torque To Cope With The Additional Weight. So Far I Am Very Pleased With The Results And I Have Got My Sorbathane Feet Back On And It Is No Longer Wobbling Around Like A Jelly. First Print Came Out Beautifully But Early Days Yet...
