UltiMaker Cura Initial Setup: What to Check First
Set up UltiMaker Cura by verifying bed size and G-code flavor, calibrate retraction (direct drive 0.8-1.2mm, Bowden 3-6mm), and compute flow multiplier from a single-wall cube. Avoid default profiles that assume ideal conditions.
Mango3D Lychee FDM: Job-Shop Production Cell Setup
To deploy a Mango3D Lychee FDM as a job-shop production cell, focus on belt tension (110-120 Hz frequency on 260mm span), keep the heatsink fan at 100% to avoid heat creep, and set idler spring compression to 2mm past contact for reliable extrusion.
NVIDIA Get3D: Practical Mesh Generation for Engineers
I've evaluated Get3D from a workshop perspective: mesh watertightness, UV atlas issues, and hardware impact. This covers what you need to know before using it for industrial slicing.
Fusion 360 Nightmares and How to Fix Them
I've been using Fusion 360 for years and these three nightmares keep showing up. Learn why parametric models blow up, how to stop it with full constraints and timeline rollback, and what to do when a model is already broken.
Three Chitubox Pro Auto-Support Failures and How to Fix Them
After dozens of failed prints, I found three critical Chitubox Pro auto-support issues. This covers why the algorithm underestimates peel forces and a manual workflow that dropped my failure rate from 40% to under 5%.
Fixing Corrupted DWG Files in AutoCAD
Learn the exact workflow to recover a corrupted DWG file that crashes on regen. From RECOVER to INSERT into a clean template, plus tips on when to fall back to a DXF round trip or last plot PDF.
CraftPrint Bed Leveling Fixes
Troubleshooting the CraftPrint's common bed leveling problems: replace the stock springs with stiffer die springs, thermal soak the bed for 10 minutes after reaching temp, and clean the capacitive sensor tip with IPA every 200 hours. These fixes eliminate elephant's foot and first-layer adhesion issues.
Fixing Shapr3D Precision and Export Problems
After two years using Shapr3D in a machine shop, three issues keep coming back: precision loss, iPad overheating, and constraint glitches. Here are my practical fixes including splitting large models and using STEP AP214 export.
Fixing Onshape Large Assembly Performance
After spending years with Onshape on the shop floor, I've nailed down three recurring nightmares. Here's how to fix the worst: large assembly performance. Use lightweight mode, split into logical subassemblies, flatten the feature tree, and check for network jitter. It made an 800-part weldment load 40% faster.
Common SelfCAD Problems and Fixes
SelfCAD is great for quick prototypes, but it has flaws like non-manifold meshes and browser crashes. Here are real-world fixes for the top three issues from someone who's debugged them.
Fixing Rhino 3D Boolean Crashes: Tolerance and History Tips
Boolean crashes are a classic Rhino nightmare. This guide covers tolerance pitfalls, history off trick, and the ExtractSrf workaround. Based on 20 years of shop experience.
Fixing Klipper Input Shaper Resonance Issues
Klipper's input shaper auto-tuning often fails due to shifting resonance. This guide explains why, provides manual tuning steps using accelerometer data, and warns about common pitfalls like loose belts and excessive acceleration.
