FAQ
TL;DR: For beginners, DipTrace’s free non‑profit edition supports up to 300 pins and is “very easy to learn and use.” [Elektroda, Steve Lawson, post #21660411]
Why it matters: You want the fastest path from idea to a reliable small CNC power‑supply PCB without lock‑in or surprise limits.
Quick Facts
- Eagle Light limits: 100×80 mm board area, two layers, one schematic sheet. [Elektroda, Steve Lawson, post #21660399]
- Eagle (2‑layer) was listed at $69 for hobby use. [Elektroda, Cody Miller, post #21660398]
- DipTrace free edition: fully functional for non‑profit use up to 300 pins. [Elektroda, Steve Lawson, post #21660411]
- KiCad: open‑source, unrestricted by layers or board size. [Elektroda, Per Zackrisson, post #21660401]
- PCB123: free, but you must order boards through Sunstone. [Elektroda, Cody Miller, post #21660398]
What’s the simplest PCB CAD to start with for a small CNC power‑supply board?
Start with DipTrace if you want an easy learning curve and a generous free tier. An experienced user said it’s “far easier to use than Eagle,” and the non‑profit edition handles up to 300 pins. [Elektroda, Steve Lawson, post #21660411]
Are there free options without board‑size or layer limits?
Yes—KiCad is an unrestricted, open‑source PCB tool. It’s powerful, free, and not locked to any manufacturer or board size, which suits one‑off CNC power supplies and future growth. [Elektroda, Per Zackrisson, post #21660401]
What are Eagle’s free‑version limits I should know before starting?
Eagle Light restricts you to 100×80 mm boards, two signal layers, and a single schematic sheet. Plan your layout and parts count accordingly or choose an alternative if your design exceeds these constraints. [Elektroda, Steve Lawson, post #21660399]
Is Eagle still a good beginner choice, and how can I learn it fast?
Eagle remains beginner‑friendly if your project fits the Light limits. Use the recommended SparkFun tutorial to learn core workflow quickly, from schematic to board layout. [Elektroda, Steve Lawson, post #21660399]
How does DipTrace compare to Eagle for first‑time users?
Several users found DipTrace easier to learn than Eagle while still offering a capable free edition. One noted, “It’s very easy to learn and use,” which helps you ship a first board faster. [Elektroda, Steve Lawson, post #21660411]
Is DesignSpark really free with no strings attached?
Yes. DesignSpark PCB is free to use and does not require you to purchase manufacturing services, making it a risk‑free tool to try. [Elektroda, Mike Wilson, post #21660407]
Should I avoid vendor‑locked tools like PCB123 for learning?
Be cautious. A user warned that proprietary, in‑house tools can lock you in. Even if they export Gerbers, you can’t port schematics or layouts later. “Personal experience.” [Elektroda, Steve Lawson, post #21660412]
How do I get my PCB fabricated on a tight budget?
Use batch services to cut costs on single boards. Options mentioned include BatchPCB and several low‑quantity PCB houses that offer quotes and file checks before ordering. [Elektroda, Steve Lawson, post #21660400]
Can I move designs between tools using Gerber files?
No. Gerbers are for manufacturing, not design interchange. They won’t carry schematic or editable PCB data, so you’ll redo work when switching tools. [Elektroda, Steve Lawson, post #21660412]
Can I simulate my power‑supply circuit before ordering a board?
Yes. Proteus lets you simulate circuits and watch behavior before fabrication. It’s helpful for validating regulators and protection circuits for CNC supplies. [Elektroda, Dharmik Brahmbhatt, post #21660404]
Is PCB‑Artist worth trying as a beginner?
It’s reported as easy to use and is available as a free layout tool. If its workflow fits your needs, it can be a straightforward starting point. [Elektroda, Dennis Bauer, post #21660413]
Any beginner video resources for Eagle?
Yes. A community‑shared YouTube channel offers Eagle walkthroughs to jump‑start your first design. Pair videos with small practice layouts for best results. [Elektroda, Bech Bej, post #21660409]
What’s a fast, reliable workflow from idea to manufactured board?
- Capture schematic and place parts in DipTrace, Eagle, or KiCad.
- Route the PCB within your tool’s limits and run checks.
- Order boards via a budget service that accepts your files and offers pre‑order checks. [Elektroda, Steve Lawson, post #21660400]
Are there low‑quantity U.S. PCB manufacturers I can try?
Yes. Users cited Advanced Circuits and AP Circuits for prototype quantities, online quoting, and file checks. Compare lead times and pricing before ordering. [Elektroda, Steve Lawson, post #21660400]
